Need help in finding RM21H9G212310. It's an A4 silver bird sole new from Buckstaff Motor Co. in Longview, TX on 2/15/1969. The last time I saw her was 1974 in Wilmington, NC. Any ideas?

I have a 1968 Road Runner and I also have bucket seats and a center console with the shifter on the floor. Just wondering if somthing isn't right. The hood that is on it has the Hemi emblems and a lot of things about the car just are not adding up, could I have an orignal Hemi car?

Look for the VIN numbers on the drivers side top of the dash (right at the corner of the A-pillar and the dash) - you'll see it as you look down through the windshield. Write it down and then come back here to this site and use the VIN decoder. Also look for the numbers on the radiator support (you may need to remove the radiator.) The numbers should be the same. If they aren't then you have a rebadged car which is a fraudulent practice and a crime. Hemi badges on the hood don't mean anything - anyone could have placed them on the car. They are available from a number of sources. You need to check the VIN and build sheet if you have it. That will tell you all you need to know.


If it is a Hemi car, the 5th digit of the VIN will be a J. It will also have a Dana rear end.

I'm rebuilding the engine in my 1972 Road Runner. I've replaced all stock for more performance parts. I was wondering if anyone had any ideas about a good torque converter.

Torque converter ugrading depends on a lot of things like: compression, cam, exhaust (headers, pipe size, etc.), gear ratio, vehicle weight and tire diameter. I mention the engine and exhaust because you said you did upgrades but how much additional power are you putting out? Do you really know? Weight and gear ratio are also highly important. A heavy car with a 3.23 or worse (2.91, say) will be a slug no matter what converter you put in it. Tire diameter plays a big part, too. A soft (2.91-3.23) gear ratio and tall tires make for low rpms and slow starts. Tall tires can make a 4.10 gear seem like a 3.55 so you need to know all this information. The best thing to do is call the tech hotlines of the various manufacturers, tell them your setup and be VERY specific as to your setup. If you don't know how much your car weighs then either find out or look at some liiterature (road tests, etc) from when the car was new and make an educated guess. Let them make a recommendation for you based on what you tell them. Call TCI, B & M, Mancini Racing (they can help you with a Mopar Performance or other converters) just to name a few. Go to Jegs website or Summit Racing's website to see what manufacturers are available and do some leg work of your own. If you go on someone else's recommendation and it doesn't pan out you'll be sorry. You need to take some responsibility on this issue and educate yourself so you can make a wise decision. Getting the wrong part here will make you very, very sorry. An educated consumer is a happy consumer.

I own a 1972 Satellite Sebring 2-dr V8 318 5.2L. I've got a couple questions? Hopefully you guys have some answers.
1) Is the Satellite considered a muscle car? I've heard a lot of opinions and would like some more. Please give list of reasons in your response.
2) Can you suggest some good websites for tracking down replacement parts? Salvage, old new stock, or reproductions are all fine with me.
3) Do you know what rims were avaiable on the 72 Satellite? Was there other options? I've got the standard rims with hub caps. I was thinking about getting sport rims and thought I might try to keep the car "stock" to some degree. Does anyone know where to get said rims at reasonable prices?
Thanks, Pat

Cars that are considered "Muscle Cars" are called so because they pack muscle(horsepower). A 318 powered anything wouldn't be considered a muscle car. You do however have the advantage of owning a body style that could have had a 340, 400 or 440 so you could simply clone your car into a "muscle car". Have fun.

I have a 1968 Satellite and have just pulled the motor. The inner fender panels are shot and was wondering if there are any things to watch out for when replacing them with new panels. Looks like drilling out all the spot welds and pulling off would be easiest. Any advice would be greatly appreciated. Thanks.

I have to walk a way from my Road Runner to think. Why when the engine is cold, and I give it throttle it back fires through the carburetor? It seems to have hesitation when pressing on the throttle. Also, it's like it's fluttering. I adjusted the timing to top dead center, helped a little. I tried a 600 cfm and 750 cfm, they both have manual chokes. And, used the metal plate and 2 gaskets on carburetor, used 2 gaskets between intake manifold. Still the same after it warms up to about 195 degrees. It seems okay. I can't really check the drive with snow on ground. I did use the valley pan with heat block off. I am frustrated, my beautiful air grabber air cleaner and base did not fit under the hood after the 440. Question: Do the 440 GTXs have air grabber hood and duct? I got an after market air cleaner with a 2 inch drop its ugly.

Sorry to hear you are having troubles. Maybe this will help.
1. The valley pan gasket you are using is definitely the wrong one for cold weather use. You need the one with the holes for the heat riser. What you are experiencing is a lack of atomization of the fuel in the intake. Cold weather cause the fuel droplets in the air/fuel mix to remain liquid instead af vaporizing. The heat in the intake helps cause atomization/vaporization to occur. As you say the car runs better when warm which is typical of all carbureted cars in the cold weather. Use a valley pan with the heat riser holes and it will help. The car will still run poorly when cold but it the carb will warm up faster and run better sooner. When I lived in Ft. Wayne, IN many years ago and drove my road runner daily it was always a challenge in winter because mine didn't have a choke at all so I had to sit in it until it warmed up - anywhere from 5 -10 minutes depending on how cold it was. Cold weather and carbs don't mix well. The bottom line is you'll just have to wait until its warmed up if you want to drive it in the cold.
2. As for the GTX with the 440 - yes they came with air grabber setups. The problem is your intake is too tall. Mopoar Performance makes an aluminum 2 plane intake that looks like the factory stocker but is a new design and makes more horsepower. It is the same height as the stocker so it should work with your stock air grabber setup. Its another $200 or so but if you want to run your air grabber setup its the only way to go. Unfortunately you'll have to spend more money but you can always sell the stuff you have now and try to offset the additional expense.

In 1973, I owned a 1969 Road Runner 383ci, red with a white vinyl top. The interior had white bucket seats with an auto trans in the console. Has anybody ran across a Road Runner with these specs?

I need help hidden parts for my 1969 Road Runner. I need magizines, web sites anything. What I really need is a new wire harness. Any info will help.

Your question has been answered many, many times in this website. First look through all the emails in this bulletin board section, current and past years. Secondly, order any of a number of information and restoration books from this website, yearone.com, Jims Auto Parts, Jacks Auto Parts, Totally Auto, etc. They will give you an excellent source of information. Then, search on the web with searches such as "Mopar Restoration" or "Mopar parts", etc. You will have more information than you will know what to do with. I currently have about 15 different parts sources in my "favorites" Most all the restoration houses, such as YearOne, have chassis parts, body, interior, electrical including all the wire harness, brakes, exhaust, engine, transmission, etc. for a wide selection of muscle cars. Good luck in your project....

I have a 1969 Road Runner. The driver side front frame rail on the inside is rusted through. It's below the shock tower and behind the K member. It appears to be ok on the bottom and the outside. Should I have a flat metal piece welded in on the inside or should I get a Safety cap? Please help me!!!

Contact Auto Rust Technicians 1-944-4444 www.autorust.com for their Frame Repair Kit for you car. They have everything you need to do the job right.

I am finishing up the resoration of my 1969 Road Runner and I am uncertain of what goes in the hole just to the right of the ac/air slide controls. It is under the dash over hang just as the ac,air slide controls are, what is suppose to fill the hole? Thanks, Mike

If you are speaking of the hole under the dash pad, in the metal part of the dash, just to the right of the temperature and blower controls, there should be either a dash map light or a panel to cover the hole. You can find the map lights (I've seen 4-5) on Ebay and the wiring hookup from the factory manual. My 68 did not come with the light (it was an option) so mine just has the cover plate.

I lowered my gear ratio to 3:91. I purchased a new speedo gear for my 727. Is this speedo gear a simple swap or do I have to be worried about a bunch of small parts comin out when I remove it? It's a 1969 Road Runner. Thanks

Many of the restoration parts houses (such as YearOne) have a kit to install the speedometer gear. It think it is just a few O-Rings and gasket. It is very cheap insurance for preventing a possible leak. When you remove the clamp holding the speedometer gear in the transmission, I believe everything just slides out together. Just install your new gear and your new O-Rings and reassemble. I don't remember it being a big deal.


It's a simple swap - piece of cake. I did it on my '71 Charger SE 440 when I switched from 2.45 to 3.55.


All you have to change is the plastic speedo gear in the transmission.


Just remember to index the cover that you pull out that holds the gear in. If you look at the area where the slots are & the tangs on the hold down bracket fit in, you'll see different markings/orientation for the different size gears.


If you haven't done this job yet I would have a pan ready to place under the speedo gear housing. When I changed the gear on my 1969 I found out the hard way that you will lose the trany fluid when you pull out the gear housing. And of course have some new fluid on hand to replace what you lose.

Will 1973 Coronet cross member fit 1973 Road Runner?

Dec 9, 2005

I just pulled the engine in my 1972 Road Runner with 440 to rebuild. I have long tube flowtech headers for it and I know it's a pain putting these in. What's the best way to drop the engine? Is it possible to bolt them on and drop it or should I set them in and then drop the engine? Thanks.

Set the headers in and drop the engine in part way. Try to bolt up the headers while the engine is about 60-60% in the bay. This might help. You'll want to remove the trans linkage (automatic) or z-bar assembly (4-speed) and also the center link between the pitman and idler arm. This will give you plenty of room to work with. The engine won't go in if you put the headers on the engine and try to drop it in.


When I did my 73, I dropped in the motor and then installed the headers. No matter what you do, you will almost certainly have to remove the steering linkage to get it in. The linkage will sit between the header and body. On my 73, I was able to drop in the motor and put the passenger side header in with no problem. On the driver side, I had to lift the motor up about 1 inch to get the header in. Make sure to put the starter in before the header or you won't be able to get the starter past the header.


I tried a set of flow tech headers and they would not fit my 1972 Road Runner...I had to go to a hooker comp header...you might double check.

I have a 1969 Road Runner. I am looking for the paint code for the flat black stripes on the hood. Thanks.

They have the paint you need. It is called Organosol and it is the original flat black paint Chrysler used for the stripes.

Dec. 7, 2005

I have installed the 440 engine my 69 Road Runner. I had all the fun I wanted getting the headers on. Anyway I got it started took for a quick spend. Need a little more tuning may need a bigger carb. I am running Elderbrock 600 cfm I have a Carter 750 cfm I may try it when it warms up. I just want to thank every body for they help at this site. The question I have is will the hood fit with a Elderbrock perfomer mainifold dual plain with the air grabber air cleaner setup without the ductwork?

With the 440 you may experience a problem with the ductwork and Performer simply because the 440 block is 3/4" taller than the 383 block, plus the added height of the Performer intake as well. You may need to invest in a drop base air cleaner assembly. Jegs has a house brand assembly in chrome with a K & N style air filter for a very reasonable price. I'm using one on my road runner (383, Performer RPM) and it fits perfectly.
As for the carb - I think you'll definitely need the 750. 440's need to breathe and the little 600 is just a tad too small. It would be great for street performance around town - giving good throttle response and decent economy - but it might be a bit too restrictive if you want to "let your hair down" now and then. Run them both and see what you think. If I remember correctly your 440 is only slightly warmed over. A 650 would be a better choice but the 750 is the normal choice for an engine of that size.
Here is a formula to help you in selecting the right carb:
Your car should probably be classified as a stock/street type of engine. Mild cam, headers, Performer intake, stock heads. It should be making around 400 hp with ease. Therefore in general it will it will use approx. 80% to 85% of its air volume intake at full throttle. Now we want to figure your max. rpm. For this engine 6000-6250 rpm should be in the ballpark with the valvetrain you are running.
Your displacement is 446 c.i. with a .030 overbore.
Now we can do the calcs. The formula is as follows:
c.i. x max. rpm / 3456 = ideal carb cfm
ideal carb cfm x .85 (85% max air volume intake at full throttle) = actual required cfm.
So then let's plug in all the numbers:
(c.i.) 446 x (max rpm) 6250 / 3456 = 806.56 x .85 = 686 cfm
(c.i.) 446 x (max rpm) 6000 / 3456 = 774.30 x .80 = 620 cfm
If you use the car primarily for cruising around and mild performance use the 600 will be a tad small but useable but if you are going to run it at the strip and want more power use the 750. As I said before, the 600 will give better throttle response (because of higher air flow velocity through the carb) and fuel economy if jetted correctly. It all depends on how you intend to use the car.

I'm looking into getting a 1968 Road Runner and there is a 1968 Satellite for sale near me. I was just wondering what all must be done to convert it to a Road Runner clone. I know it isn't much but just would like to know the exact differences. Thanks.

The Road Runners had the front sway bar, 11" brakes, heavier rear springs. Some '68 Road Runners had a rubber floor mat instead of carpet.

Also the road runner had larger diameter torsion bars and strut rods, the 383 road runner engine (335hp as opposed to the 330hp optional Satellite/Belvedere engine) standard or optional 426 HEMI engine, 4 speed A-833 transmission standard and optional heavy duty TorqueFlite automatic transmission, 5/16" fuel line standard or 3/8" on the optional HEMI, road runner horn (painted black in 1968), 8-3/4" rear end with 3.23 gears standard and optional Sure Grip and gear ratios. The 1968-70 road runner was based on the low line Belvedere line while the GTX was based on the upscale Satellite line. The road runner also used a slightly different hood from the standard Belvedere. The road runner hood had 2 "power bulges" (1 each side) which denoted the engine size (383 or HEMI) with badges in the power bulges. There were also trim options which included a stainless trim panel for the rear of the trunk among other things. There were more differences between the 383 and 426 HEMI cars in terms of suspension and chassis components as well.

Brakes were 11x3" drums front, 11x21/2" drums rear, manual adjusters, heavy duty rear springs, heavy duty torsion bars, front sway bar, performance hood, Road Runner badges on trunk, doors and dash with proper decals (B & W for 68, color 69 and up). Engine was different from other 383's. Base Road Runner motor was the 383, it had 440 (906) heads, windage tray, 440 exhaust manifolds, 440 spec. cam and Carter AVS carburetor. 4 speed transmission had the 11 inch clutch. Only other engine was the Hemi in 68. Interior had limited options for seat, only bench in 68. Some had carpet, some vinyl mats. There are other small differences but these will give you a start. The GTX options are another entire selection.

Another option on the 68 road runner was the power disc brake setup. This option used Bendix 4 piston fixed calipers and of course was power assisted. these brakes were available from 1966 to 1969. In 1970 Plymouth switched to full floating calipers with single pistons.

I need help!! I am trying to locate my first car which happened to be a 1970 Road Runner. I have the VIN which is RM23N0G144822. It was sold new in Illinois any help would be appreciated!!! Hopefully it is not a Pepsi can somewhere!!!! Thanks.

I have a 1970 Road Runner with the stock looking basic steering wheel. I want to mount a 1969 Road Runner wood wheel on the car. Since the columns are different in diameter 4" verus 4 1/2" because I would think they needed more room for the lock on the column. I know the wheel fits, but who or where can I get the spacer or adapter to cover the space difference. It would look terrible if I mounted it without. You can see the signal switch from the sides becuase of the 1/4" space all around. If anyone can give some pointers I would really appreciate it. Regards, Dave.

Can anyone give me information on (V6W) 'Sport Stripe' on a 1969 Road Runner? Runs horizontally at fender, door and quarter seam. The Year One stripe that is available does not seem like the factory original stripe that I had on my new '69 RR.

I own a V6R car. The stripe runs horizonal about a half inch below the fender, door and quarter tops.

Hi, I have a 1970 Road Runner. 383, 4 spd car. non-air (LYNCH BUILT CAR-I ASSUME FOR CAL. BUT I'M NOT SURE-THAT"S WHERE I AM). Most orig. Stuff is there. But since no one seems to want to pay what I believe project is worth. I guess I'll restore it. Need to know how do you tell if car was factory equipped with Holley or Carter (AND CAN I GET BOTH #'S). And what are distributor and alternator #'s. And fan and fan clutch if applicable. Note. Would a 1970 383 2v, or 4v -auto. Out of a Satellite have correct alt. Or dist., or fan, valve covers, or PVC and hoses system? Also, I guess these cars did not have smog, even in Cal? Also, please tell me differences between 1970 Road Runner, Satellite, and sport Satellite in grills. Hopefully it's just paint color. Note- I have build sheet if that helps and I'd like to know what wheels car came with. If steelies. Are small caps with tri-bar logo in center correct? Or plain? One last question. Search showed me graph of cars saying a large portion of cars came with buckets (60-70%). Yet, in real world today. Most cars left seem to have bench? What are the real % numbers? And are there 2 levels of interior trim? Whether bench or bucket, do they all have the silver piping with black seats? And is a non-console very common with 4-spd and buckets (that's what this seems to be). If anyone is real good at this info, yet doesn't like to type. You can always send a phone #. HELP- I'm a Ford/GM guy. But I'm a pro resto. person and I believe there's only one way to restore-FACTORY CORRECT. THX -in advance for any help. C.F.

Does anyone know the torque specs for a 1972 Road Runner with the 440?

Chiltons says, torque 380 @3200 RPM , HP 290 @ 4800 RPM . Compression in 72 went down to 8.20:1.

Nov. 22, 2005

i got a 1970 Road Runner with factory air, I need the schematics on installing the brackets and lines, is there any one out there that may have the schematics on this? I'd be grateful and I'm sure there are a few more that has and needs the diagram. If so please send me a copy. Thanks in advance. Art

I went too fast, buried the speedometer and broke it. I am going to have Yr 1 rebuild it, but would like advice on how to take it out. Do I remove the lower plastic dashpad first? Do I have to remove the whole instrment cluster? I've done this several times on a Dart, but this is more difficult. It's a 1969 Road Runner. Any advice is appreciated. Thanks

Yes you have to remove the lower dash pad.Also unhook the speedo cable, and gently pull the large wire plug off the back of the cluster. There are several screws on the bottom of the instrument cluster that you can't get to with out removing the lower pad.

Nov. 21, 2005

I'm trying to determine if there are any 1970 Road Runners with the same or later build date than mine which is 07/24/70. I've seen higher serial numbers but those cars were all built earlier than mine. Thanks!

Nov. 16, 2005

I have a 1969 383 Road Runner. What headers should I get? TTI or Dougs? And, how is TTI's Exhaust system and how about their tips? Or does someone else make 2 1/2" tips? Need feedback quick!!!

As far as I am concerned, TTI is the only choice. Their entire system is great. If they don't have a 2 1/2" exhaust tip, I think YearOne has one. They look just like the factory units, just with a bigger input end.

Nov. 15, 2005

I have removed my 383. I notice the drv. side motor mount broke again it lasted maybe 2 years. On 440 I plan to use mity mounts cost 99.99. Also planning on installing an Elderbrock alum hi cooling properties 119.00. It looks like every part I touch needs to be replaced. Any way the question I have is it possible to install the 440 with bell house and tranny as one unit? Or, would I be better off the bellhouse and engine and then install tranny? I am doing by myself. This is a 4 speed car.

If you are doing the work yourself I'd recommend installing the flywheel, clutch assembly (with t-o bearing and fork) and bellhousing on the engine and then lowering it into the engine bay slowly! It will be an extremely close fit front to back so you'll need to be able to tilt the tail end of the engine downward. You may find clearance issues with the t-o bearing fork so watch out for that as you lower it all in. Make sure the steering center link is securely in place and have a small block of wood handy to place between the oil pan and the center link so you won't crease the pan by letting it rest right on the center link. Get the car as high off the ground as you can with some good quality jackstands and install the trans from underneath using a good transmission jack and make sure the trans is empty of oil - otherwise you'll get it all over the garage floor. Fill the trans with oil after it is all bolted up in place. I speak from experience here. To put it in all as one unit would be too much for 1 person in my opinion. It is extremely heavy and you would need to really drop the tail end to get it in. You can't work the hoist and direct things into place alone. If you can get help I would highly recommend it.

Nov. 13, 2005

I was wondering if anyone had any breakdowns on how many 1973 Road Runners were produced with the 340 and either the 4spd or auto. trans....I have found a red with black stripes and black interior Road Runner near me and was wondering how rare it is.

Nov. 7, 2005

I have a 1972 Road Runner that originally came with a 400-4-spd. In my quest to find a motor for it, I ran accross a 426 hemi which I bought because I couldn't pass it up. I am having the Hemi professionally rebuilt by a very reputable racing shop. My question is would it be worth putting this in my 1972 Road Runner or would it be better to get a differant year. I am also not sure what, if any, environmental guidelines need to be followed. Does anyone know what guidelines I need to follow, and if it would be worth it?

Since you don't have the original engine, I wouldn't think twice about putting the HEMI in.

I have a 1969 440 Road Runner with drum brakes all the way around. I have some wheel and tire questions. I am buying a set of 15x7 Cragar wheels for the front and back. I am not sure what backspacing to buy 4, 4.25, or 4.5 inch. Most of the wheels I am interested in are 4.5 inch backspace, but I don't know what to buy. Also, the wheels require "conical seat" lug nuts. What is the thread pattern, size, and length of the studs and does the 69 Road Runner have reverse studs on half of the car? The last question is tire size. I am putting the same wheel size for the entire car and I would like the tire size to be the same. Any help would be greatly appreciated.

Concerning your question about wheels for your Road Runner - 15"x7"x4.5" backspacing will fit just fine. I am running 15"x8"x4.5" backspace Magnum 500's on the rear of my 1969 Road Runner with 276-60R15 B.F. Goodrich tires and the fit is perfect. The driver's side does have reverse thread studs but you can replace them with studs from a 1970 model if you so desire. The conical lug nuts are stock type lug nuts which you should still be able to find with some diligence. I would suspect that stock length studs will work just fine. As to tire size I'd go with a 235-70R15 tire. I have them up front on my Road Runner on 15"x7" Magnum 500's and they look really nice. Not too fat, not too skinny. I think they'd give the car a nice balanced look. They are 28.5" tall and about 7"-8" wide.

HELP...I need to know which Dog Dish is correct for a 1969 Road Runner. My car was produced in LA code 99 Bahama Yellow and came with painted wheels red line tires and dog dishes. I need to know the correct Dog Dishes for this car and where to find them. Thanks for your help, Dave M

Check on eBay - they usually have them. They are small hubcaps that read "Plymouth Division" on them. I'll take a pic of one of mine and forward it to you if you like.

My husband would like a price list of a 1975 Road Runner in very good shape pupple in color. Thanks Anna

Go to your local book store (Barnes and Noble, Borders, etc) and look for a book called The Old Car Price Guide. You'll find everything you need to know in there concerning prices based on condition. Unless the color of the car is extremely rare it won't affect the value all that much, especially on a 75 Road Runner because they just aren't that popular with collectors. You should be able to find a good deal on a 75 Road Runner but it may be very difficult, if not impossible to find one in Plum Crazy purple. You may just have to buy what you can get and have it repainted. There weren't a lot of 75 Road Runners made which makes them somewhat rare but by the same token they aren't a popular model now (and weren't when new - hence the low production figure) so the value isn't extremely high on them either. In any case I wish you success on your search.

I have a 1969 Road Runner that I am fixing the brakes on. It has manual brakes and drums all around. I have replaced all wheel cylinders and the master cyclinders. All the lines are clean and free flowing...except the two black front flex hoses that connect to the wheel cyclinder from the metal lines. I either need to replace them or work on them but I am having trouble removing them. I can remove them from the wheel cylinder and I can remove the metal line coming into the hose but I can not remove them from the frame mount. Any help would be greatly appreciated. Thanks.

There is a U-shaped clip on the fitting were you took the metal brake line from you snap off the U-clip and it should come right off. Hope this helps.

I'm looking for the right argent silver paint to restore my tail panel on my 1969 GTX, I'd like to find the coarse silver metalic paint that was factory, and also before I remove the red beltline reflective red stripe I need to know where to fine new red pinstriping, because the factory stripe is reflective at night. Any help please email me, I'd like to do this soon.

Totally Auto handles this paint, along with a lot of other specialty paints. They specialize in Mopar only restorations. I don't have their number handy, but they advertise in the mopar mags.

Year One will have the Argent paint and may have the reflective tape stripe as well. Go to www.yearone.com to find out.

I have a 1969 Dodge Coronet with a 340, it will run for quarter mile good then cuts out what should I do with the timing, right now it is facing passenger firewall should I turn it 180?

It is not that simple. If you turn your distributor 180 degrees your car will not start, it will possibly break or bend parts, backfire, burn to the ground, etc. You get the point. You left out all the important data. If your car runs through the quarter OK then starts to miss or quit it can be a number of things. You could have fuel tank, fuel line, fuel filter or carburetor problems. You could have internal engine problems such as valve springs. You may have ignition problems. You didn't say if you had points or electronic system. The old points system takes a lot of setup to get them to run OK. The electronic systems are much better but again they need to be setup to operate good at Hi-Performance levels. You can even have exhaust problems from a too restrictive exhaust flow. There is more but this gives you a good start.

I have a 1968 Road Runner. Car is said to be one owner 440 car. I have no VIN tag on dash or fender. Don't have build sheet under seat. The mice like it to well all I have left of it is the last 8 digits. Can anyone help?

It may well be a Road Runner or it may not. I'd be very wary if there is no VIN or fender tag. Its easy to pass off a clone car if the documentation is missing. Also, someone swapped in the 440 sometime in the past because the only engines available in the 1968 Road Runner were the 335 hp 383 or the 425 hp 426 Hemi. You definitely need to find some documentation on the car. Check the radiator support bulkhead for number stampings - the VIN should be there somewhere.

Am trying to find out the exact location on a 1969 Road Runner for the running bird & standing bird. I am aware the running bird goes near the head light L/h & R/H and the standing birds go 1 on the trunk lid & 1 on the dash. But I am trying to find an exact location. Thanks Joe

I have a 68 Runner and the standing bird decals are on both doors, just in front of the Road Runner badge. The running bird decal is on the right hand side of the trunk lid. The other standing bird is on the dash just to the right of the Road Runner dash badge. The 68's had the black & white birds. The 69's had color. I am fairly certain that the 69's were at the same locations. I have never seen a 69 with anything on the front fenders. I think the '70 Runners may have had a bird on the front fenders. Check out any of the several restoration website for Mopars, especially musclecarrestorations.com and checkout the pictures of their project cars. You may be able to see the exact locations. There are also many books on Mopars that detail the restorations or are just a pictorial of many of the cars. If you don't have any luck, let me know and I'll check some of my books and let you know for sure where they go.

I have an opportunity to buy a 1973 Plymouth Sattelite. It has a 318 engine. I'm not a car buff, but I like to buy and sell things. I can get the car for $600. Can someone please tell me what to look for and what the car might be worth. Here's some info. Runs, drives and looks good. Front seat is torn, but looks OK. Carpet and headliner were pulled and look good. Large crack in windsheild. Dual straight pipe exhaust (new, loud) White vinyl top is in good condition. Tail light lenses need to be replaced. If this is a good opportunity, please let me know. Thanks.

Who owns my old 1970 Hemi Road Runner? I am pretty sure that the serial number is RM23R0G150945. I sold it in '91 (roughly, maybe it was '90?). It is dark green metallic, 4-spd, super-trac-pack, air grabber, pb, ps, etc.; all the good performance options. I am working over in Russia right now, but wondering about the possibility of getting the old Mopar back in the garage in Graniteville. If you have any info about this car please Email me at bcobrathomas@aol.com or call my wife at 803-646-6257.

I have bought a 1974 Plymouth Road Runner for my son's 16th birthday. It is in excellent shape except for a few cracks in the dashboard. Where would be the best place to find a dashboard cover for the car? Thanks! Sonya

Year One (www.yearone.com) has just what ou are looking for. They have replacement dash pads or a dash pad covers. If you want to do it right get a new dash pad - if you don't have the money for a new dash pad then get the dash pad cover instead.

I have a 1972 Satellite Sebring Plus. My problem is in the fuel system. The engine is a 400 2 barrel. The engine starts and idles but after about 15 minutes, the engine dies and won't start again for a while. So far as I can tell, the fuel pump stops pumping gas to the carburetor. I have a clear glass fuel filter right before the fuel pump. When the car is first started and running, the fuel filter is full but after a while the filter runs empty and the car just quits. I just put a new fuel pump on and a new carburetor. Another thing, after the engine warms up and the butterfly on the carb is all the way open, there is a hesitation when you punch the gas. I have to close the butterflies halfway to get rid of the hesitation. It seems I have to choke the carb because there is not enough gas getting to it, or too much air coming in. Shouldn't the gas filter stay full when the engine is running? Also, to rule out the possibility of the gas tank being clogged up, I I ran a hose straight from a 5 gallon can of gas to the gas filter inlet. Still the same problem, when the filter goes dry, the engine quits. Could I have gotten a bad fuel pump? Is the fuel system somehow vapor locking? Is the fuel pump breaking down after it runs for a while? Someone must have had this problem before. PLEASE HELP!

Since you're doing the 5 gallon gas can bit, I'd try the fuel filter first (since it's the cheapest), but I suspect the fuel pump. Another thing, while you have the fuel pump off, check the little push rod that runs the pump off the cam. Also check the lob on the cam that moves this push rod. I've heard of these getting too worn to work the pump.


I had the same problem with one of my Mopars. It turned out to be a corroded fuel line and gas tank. I tested the line by putting compressed air through the line after disconnecting it from the fuel filter. In other words, forcing air back through the line the opposite way the fuel flows. Make sure you take the fuel cap off and have someone listen for bubbling in the tank through the filler tube. If you can't hear the bubbling, either your line is plugged up or the pickup in the fuel tank is plugged. If that is the case, you may want to determine why. Could be you have something in the tank causing the problem.


You might have a clogged fuel line, I had a simular problem and it was the sending unit in the gas tank.

Has anyone here ever installed the rear glass on a 1969 Road Runner? My body guy took the glass out and I'm not too confident in having him put it back in. I can't seem to find repro rubber or any thing else for that matter. The shop manual mentions some rubber spacers but it is unclear if there is rubber weather stripping or if it is just adhesive. Any help or advice would be greatly appreciated.

The rear windows are held in w/ adhesive. This can be pick up at any body supply place. I don't know if the rear windows have the small rubber spacers or not. I know the windshields on C Bodies (which use the adhesive) use two small rubber spacers.


I would recommend Windo Weld Ribbon sealer.

Hey guys, I need some help with a Volare Road Runner. I picked up a 1979, 360 car, all orig. and it's gorgeous. But, it has these wild orange strobe stripes on the hood. They will need to be replaced. The car itself is a dark chocolate color, all original, but faded. Any sources? Pictures? What striping options were there in 1979? Any help much appreciated!

I 'm responding to your add about the 79 rr. I've never seen one with those color stripes and would love some photos. The proper stripes are silver or gold. I know alot about these cars - own 5 F-bodys.

68 Road Runner: I have an issue with the bulkhead disconnect located on the firewall. One of the contactors is in need of replacement. It so happens to be the battery voltage (w/ fusible link) going into the car! (middle bar of bulkhead, location J) Can you purchase just the bulkhead disconnect? If so, any suggestions where? I'm afraid I have to purchase a whole new dash harness? Thanks.

I have a chance to buy a real muxcle car-a 1970 GTX 440 6 pack car. However, I want to make sure it is real and not a clone or rebodied car. I have the VIN number and it checks out according to the information I have pulled up. However, can I confirm it any further, such as pulling the information off of the fender tag? If I get that information, where do I go to check it? If that all checks out, is there any other way to be sure this is real, since tags can be removed and replaced I have been told? Your help and response would be appreciated as I really would like to buy the car, but not at the expense of being ripped off for a clone that is worth a whole lot less than what I will be paying. Thanks Bob

The VIN 3 of the car will be on the VIN tag in the dash, on the fender tag, the radiator support, and under the weather striping in the trunk.

I have a '69 Hemi RR that came equipped with the deluxe interior. The car has been mostly restored by someone other than me. I found a "before" picture and can see a piece of chrome across the back of the trunk, but my car now has no sign of it. Do I need to add the chrome to make the car "correct?" I'm hoping someone will say "no" because I do prefer the way it looks without it. Also, the interior color is B7 with two-tone B5/B7 door panels. I believe the inner sheetmetal on the doors should be painted B7, but everyone I talk to says B5 to match the exterior color. Who is correct?

The 1969 had no chrome on the trunk lid. The 1968s did. I believe the upper doors should be painted to match the exterior blue.

Can someone help me on what 4 speed trans came in the 70RR 383. We found a 383 out of a 70RR but it came with a 3 speed. I believe we have all the other goodies that went with the RR. The moter and trans were sold years ago because the guy never cam back to pay for the moter work.So my son bought the car and we got all the papers from the owner 10 years after I guess that was luck that we found him 800 miles away. I think its an A833 but the A and B bodies have me confused because I am a Ford/Chevy old man!!60.I saw some on eBay out of all types and I don't need to buy one thats got the wrong tail shaft and fits in the Cuda and not the biger car? the ones on eBay are not selling I guess because of what they want for them but its a start! He does have a 4 speed and I think its date code was 66 and its a heavy one? Looks like one maybe for a truck but its not a top loader so maybe they just built them heavy and meaner back then? Well I guess I blabed enough but any help would be great. Thanks, Duke in NC

Your 1970 Road Runner would have had an 833 4-spd and it will measure 27 3/4 in. long and the place where the shifter bolts to the tranny will be on the front of the tail shaft on the drivers side. Some 833 4-spds have two places to mount shift linkage and the other location is for the e-body cars, but it will work on your car if it has both areas for mounting the linkage. When measuring the tranny meas. from the flat spot that comes in contact with the bell housing and the end of tail housing not the shaft.

What size drum brake's do I need for my 1969 GTX Road Runner, 2 in front and 2 in back. Also a 383. Any help would be geatfully helpfull.

The 1968-69 Runners came with 11x3" front drums and 11x2 1/2" rear drums. One note of interest, I just went through the brakes on my 68 restoration project and it appears that some came with self adjusting brakes but some also came with manual adjusters. Mine had the manual adjusters and the correct parts were a little harder to find. Most parts are still available through various restoration suppliers.

Oct. 3, 2005

Hi, I am not a Mopar guy, but I have a question about engine colors. I notice that some 340s & 383s are painted Blue while other were painted Orange. Is there a rhyme or reason to this? Thanks

Yes, indeed. If a big block was painted turquoise it was an a/c engine. All hi-perf. big block non-a/c engines (in B-Body cars at least) were painted Hemi orange. All non a/c 383's in Road Runners were rated at 335 hp. All a/c big blocks were painted turquoise and all 383 a/c engines put it 1969 Road Runners were rated at 330 hp not 335 hp according to Galen Govier. This may be true for 1968's as well. As far as I know all 340 engines were Chrysler Blue - if anyone else can correct me on this please do.


The 383 HP engines in the 68 Road Runners that were rated at 335 HP were all painted turquoise, whether A/C or not. I believe in 69 the non A/C engines were orange and the A/C engines were turquoise.

Well here's my story. Upon taking my air cleaner off I dropped the wing nut into the carb, so not knowing it was in there I started my car and instanly shut it down after hearing this wing nut buzzing around. Anyway, I had to start breaking down the motor with this in mind I will be porting and polishing with a valve job. I don't know how the previous owner got the header on (driver side), but I had one way to get if off to remove the head (sawzall). I will be getting a small hi tourq starter. My question is what brand header will be a little easier to install without my sawzall or tumms? Thank you.

tti makes the best headers for the big block Mopar. They fit like a glove and are an easy install - but the drawback is that they are very expensive. I have a set on my car after 2 unsuccessful tries at installing Hedmans. The tti's went on with from underneath absolutely no problems. All we did was put the car up on high jack stands and rotate the steering wheel so as to get the pitman arm and idler arm out of the way. I used the studs for the exhaust manifolds (left them in place) and removed the spark plugs for clearance. If you still have the original studs I'd recommend replacing them with new ones. At any rate they are extremely easy to install, but like I said, you'll pay a rather high price for them. You get what you pay for.

1969 Road Runner does any one know if there is a gasket or anything that goes between the 1/4 panels and the extentions? Thanks

I'm pretty sure Year One makes this gasket. I need to find out also before I get my '69 painted.

I've finally taken my 1969 Road Runner out of storage...mechanically it's rock solid (originally a 383 4-speed car, now a 440/automatic). The biggest problem I have is there is a LOT of rust that wasn't there when the car was parked. The previous owner put an (incorrect) after-market vinyl roof on the car, and there is so much rust under it, I think I'll have to replace the entire roof. I'll also have to replace the front valance up by the windshield (where the cabin fresh-air intake is). I know other parts can be purchased through Year One, and a host of other parts houses; however finding these parts is proving a challenge. Any help in finding a rust-free roof would be greatly appreciated.

I have a 1969 Road Runner with a vibration in the drive train. Both u joints fell tight. There is a little play in the spline that slips in the tail shaft. I have a manual 4 speed. #1 If the problem is in the tail shaft what would it be and can it be fixed? Also do I need to pull the whole transmision out if that is the trouble?

Drive the car down the road and when it starts vibrating take it out of gear (slip it in neutral, let the motor idle and let the clutch back out). If the vibration goes away it is may be a motor imbalance, the flywheel or a clutch balance problem. If it still vibrates it may be the driveshaft, u-joints or a loose pinon bearing in your rear end. If you determine that the problem is drive train, it could be you have a bent drive shaft. Take it out and have a driveshaft shop put it on their balance machine and check it for run-out and balance. If it is OK, replace the tail shaft bushing in the tail shaft of the transmission. If it still vibrates, check the pinon angle. (If you have the car jacked up in the rear it can sometimes cause a problem.)

Sept. 28, 2005

I have a 1969 Road Runner 383 and I would like to find a chart that shows how the fuel system goes together. Anyone know a place I can look?

I'd suggest a shop manual if you can get your hands on one. If you can't find a printed one you can go to Mopar Manuals on CD-ROM by MuscleCARS, LLC www.moparmanuals.com 203-237-4795. These are original factory service manuals for 1914-1989 Mopar vehicles.

I recently acquired a 1968 Road Runner. The trough that the rear window and bottom reveal trim is attached to is rusted out in spots which makes for a rotted trunk floor. Is there an outfit that sells a replacement trough? I'd rather cut out the rusty one and weld in a new one if I can.

I know year one and others make the corners, but I don't know if the whole channel is repoed. Might have to get a used one, or year one makes the whole panel that goes between the window and trunk lid.

I have a 1970 Road Runner hardtop six barrel car. It originally came with standard power buldge hood no stripe. It appeared I had the original trunk lid before I restored the car. It had the Road Runner standing bird decal to the right of the trunk and metal Road Runner plaques with studs on the decklid. My question is if you ordered the car and requested the rear deck lid stripe to be deleted would you have gotten just the regular plaque with standing bird instead? Also, was the rear deck stripe standard on all hardtops? I do not see very may 70 birds without stripes on the rear deck, and wonder if you had to request no stripe. Thanks in advance!

Hello, do you know if petty blue (or a similar color) was offered on 69' Road Runners? I used to own one this color in the 1980's, and it was an original car from this area, my older brothers knew the car and owner from day one. Anyway I heard Plymouth only made a few (way less than 100), but in the "b-body restoration guide" showed all the colors available for 69' and there were a few blues but none like this color. Maybe it was a special order color, would this be the same as basin street blue? even this color was not listed as available in 1969. I would like to have the color code # for this. I located a 69 Road Runner around here, and it is black but under closer examination I can see that it was this same color blue also. If you have a color code # for this I would like to go back and see if the fender tag shows the same #. I will probably buy this car either way, but I would like to know if this is a rare color or not. I have only seen one ever, the one I used to own, and now this one I found. I would appreciate any help. Thank you, Regan Ticer, Safford AZ
Recently I discovered a black Road Runner body, its a 1969 and I found that it too was this same blue color when new. If you know anything about this I would appreciate the information. If I can get a code number I want to go back and inspect the fender tag. This car is buyable and I will probably take it no matter how rare the color is, I would sure appreciate any help.

I believe the Petty Blue was a special order and it should have a paint code 999. I had a 69 that was orginal Petty blue and that was what was on the fender tag, hope this was helpful.

I have a 1969 Road Runner and the key broke off in the ignition. Paddock and Year One only sell ignitions for 1968 and 70 not 69. Does anyone know where I can get one or if the years are interchangable? Thanks for all your help.

Try taking your ignition switch to a locksmith. Should be cheaper than buying a new switch. The '69 switch was a one year only. Different size (where it fits thru the dash frame) than the '68.

Does anyone know where I can find aftermarket or original fenders, front and rear valances, trunk lid and rear quarter panels for a 1974 Plymouth Road Runner? I also need interior dash parts, dash pad, knobs, console...etc. I can't seem to find any decent ones.

Check with Hemmings Motor News, Mopar Collector's Guide, Mopar Muscle Magazine, Mopar Action, etc for parts vendor references. Check your local bookstore if you can't find these magazines on your local magazine racks. Also do web searches for what you want. I know I can find hundreds of sources at the click of a button but its easier for me because my rr is a 69 and they are easier to find parts for than a 74. Still with just a little leg work you'll have more sources than you can check.

What were the production numbers on 1970 Hemi Road Runners auto and 4-speed?

Sept. 4, 2005

Quick question. I am looking for a center console for a 1970 Road Runner w/4-speed. I see a lot of good automatic consoles, but no four speed consoles. Are they the same except for the top plate? I have a good top plate on mine, but my console has the usual cracks and I am wanting one better. I know the four speed cars have the center hump so I am not sure if the consoles are the same and will interchange. I could always resell the top plate if needed. Thanks Guys! Dan

The only difference is the four speed console is cut out on the drivers side to clear the shifter hump. you can cut yours to clear the hump, and save a lot of $$. I believe year one or the paddock sell the piece that covers the hump, or you could just use the carpet to cover it.

I'm restoring a 1969 Road Runner and I have a problem with the break rod lining up with the brake pedal. The car has a power brake booster and disc brakes (after market) Wilwood I think. If any body knows or thinks he knows what my solution might be I would greatly apreciate your help! Thank you.

I had to basically make a setup for mine, Good luck with your back this is a tough place to get comfy. I bought a rod from Mopar perf $ 70 @ summit and made it work. Is the fulcrom intact?

Aug. 26, 2005

My fuel gauge does not work. I have tried to get to to work but it just keeps going way past the full mark. The tank is full and on level ground. Any suggestions woulg be great.

Check or replace the small metal voltage limiter/regulator on the back of the dash cluster behind the fuel and amp gauges. If it is bad it can cause your problem. The limiter drops the voltage to both the fuel and temperature gauges to about 5-6 Volts.


Your float on your fuel gauge may be out of adjustment. The first thing i would do is pull it from the tank,hook the wire up and move the rod manually.if the fuel gauge moves then your unit is out of adjustment. you can correct it by bending it to where it registers full with a full tank. Also check when its disconnected and see if the gauge drops to empty. if it doesn't you have a shorted wire between the gauge and the sending unit. hope it helps


Have you checked the float? Chances are it is filled with gas sending a false signal through the sending unit. If it is, dry it out and seal the hole/crack. Mine had hairline cracks allowing gas to seep into it. I recommend you first check to see if there is electrical current (power) running to the float. If the float is getting power, then check for cracks / holes.

How do I get the steering wheel off of my 1969 Road Runner? I don't see any screws for the horn ring. Do I pry the plastic Road Runner bird off of the center first to access the nut?

Yes, you need to remove the plastic "beep beep" center medallion to reveal the attaching nut. Remove the nut and the horn ring comes off. Then remove 3 screws to get the backing plate off and then 3 more screws to get another ring off. Disconnect the horn wire and then use a steering wheel puller to get the wheel off.


Most of the horn buttons twist off counter-clockwise. Once it is off you will see the large nut holding on the wheel. Use a wheel puller, don't try to pry or beat it off. The safety portion of the collapsible steering column can be damaged.

Its all most time to install 440 engine. The question I have is can I remove, install the engine with headers still connected to the engine? (2) I still wonder what horse power I am going to make with 1978 remanufactured 440 long block 1966-72 forged crank, 443 intake, 465 exh. dur.@.050 214 int. 224 exh.750 cfm carb. 3/4 inch headers Edlbrock dual plane manifold msd distrub., ignition, stock 906 heads. 4 speed trany? This is geting very pricy. I got about 3,500 in to this project is there more I should do before I install the engine?

I would not recommend trying to install the engine with the headers on it. Just put the engine down in the engine compartment about 2 " off the mounts and install the headers before you lower it all the way down. It will not fit with the headers on the engine. Depending on the header brand you may have to do some "creative field engineering" to get them to fit. Test fit them on the engine before you try putting them when the engine is in the car. It might save you some real headaches. If you bought tti headers don't worry about it. They fit great. You combo sounds pretty good but I don't think it will make much more power than a stock 440 - maybe 400 -410 hp instead of the stock 375. It will feel and run better than stock for sure but the cam is somewhat mild and the unported heads will not help. The stock cam was very close to yours but had .450" intake/.455" exhaust lift with advertised durations of 268 intake/284 exhaust. The msd ignition Edelbrock intake (Performer or Performer RPM?) and Holley 750 will help some as well. The Performer RPM makes more power than the Performer but the Performer is a nice intake and will run smoothly.


You cannot know the HP till its in, tuned and on a dyno. It could have 250 or 450. Took me 2 months to totally tune my 383. No you must lower the engine in bolt up the rear mount and then install the headers, then depending on which headers you have you will deal with the starter and possibilities of suspensionparts being in the way.

I have a 1970 Road Runner, but need lots of different body parts. Is there a place to buy doors, hoods and things like that? I am new to this and I am really having a hard time finding anything. I have somebody that will do all of the work I just have to find the parts. Thanks for any help.

Get these magazines: Mopar Collector's Guide, Mopar Muscle, Hemmings Motor News
Your local bookstore should be able to get them for you. These magazines will have lots of parts vendors for you to check out. Unfortunately no one is making replacement steel hoods but you can find fiberglass replacements if you want to go that route. The best you can hope for is to find good used parts. There are replacement rear quarter panels, trunk floors and extensions available. Check with Year One (www.yearone.com) and The Paddock (www.paddockparts.com) Year One and The Paddock also have lots of other parts available as well.


i am doing a 69 that is half done...the parts are not too hard to come by...I would also suggest a parts interchange manual for parts that fit a lot of cars.you can save a bunch that way.

My fuel and temp gauges stopped working. Thinking it was the voltage limiter I replaced it - still they do not work. On the instrument panel there is a condenser with a wire that is not plugged into anything. Can anyone tell me where this wire goes? Also where the ground is for the instrument panel?

The wire from the condensor goes to the middle prong on the vltage limiter.


For the condencer part of your question go to the 2003 year bulletin board listings and check out the Donald Costley question just past half way down the list.

I`m looking for a factory holley carb for my 1970 383 Road Runner, I can not find a site that list the #s, I only find carter #`s, Any help greatly appreciated, thank you, Some jerk took a few parts off after I paid down payment.

I have an old Chiltons book from the early '70s. I know it lists the Carter #s, should have the Holleys. Do you have a 4 gear or auto?

I have replaced the 340 with a 440 in my 73 Road Runner. The car I took the 440 out of did not have the Mopar electronic black ignition box in it, but did have a one pickup style electronic distrubutor. 440 ran when I pulled it out. I have been unable to get a spark to the plugs even though the coil has power. Any suggestion?

The dual ballast resistor used with the Mopar Electronic ignitions have two purposes. One section of the resistor is for the ignition coil. It drops the voltage down so the coil will not burn up. The other section of the resistor applies the power to the ignition box for its electronic operation. The internal circuitry of the ignition box takes the place of the old ignition points making and breaking the current through the ignition coil to create the high voltage spark. Make sure your ballast resistor is good and that you are getting voltage to both your coil and to the control box. If you can obtain the installation instructions for the electronic ignition kits that Mopar sells it has a great electrical diagram of the system. It could help you in troubleshooting your problem.


Did the engine have the electronic ign control in the air cleaner, if so youll need a different dist. Have you checked your engine and body ground wires?


See Mopar Muscle magazine's lastest issue (October 2005) for an article they did on the electronic ignition system. This ahould fix you right up.

I have a '69 Road Runner, 383 auto. 3.91 gears. The car runs very warm, 190-200 plus when at lower speeds, and somewhat higher at highway speeds. If I shut the car off it could go up to 230+ and become very hard to start and keep running until it cools off. But what I find odd is it dosen't boil over. It has the usual antifreeze, water mix. I've been told that I could retard the ignition a bit to help it run cooler, would that help? I was also told that some black discoloration on the intake near the heads, indicates a blockage in one of the passages that he says might add to the problem and it needs to be opened up. Are these valid ideas, and worth trying? Any suggestions are appreciated? Thanks

you might try a 180 degree thermostat .The reason its hard to restart after running is that the gas in the carb is boiling off or vaporizing and it takes awhile for the fuel pump to refill the carb.

Does anyone know where I might be able to find wiper pivots for a 1969 Road Runner?

Aug. 2, 2005

Wanting to know if there are major differences between the 71 and 72 Road Runners. My dad has an old 72 that he wants to restore, and I found an old 71 that we could use for parts, but don't know how many/if any parts would be the same. Thanks Ron

There are many parts that will interchange. I'm not 100% sure, but I believe that the grill and tail lights are the only major differences.


The grill on a 72 RR is rare and the grill in a 71 looks like the 72 satellite but is blacked out! And i hope your dads 72 has nice taillight lenses as everyone i have found wants a fortune for them and the 72 has a lot meaner looking taillights!

July 31, 2005

I have a 1969 Road Runner with the turn lamps on the fenders, does anyone know if there is a replacement kit for the light, socket, etc. and if so where I can get it. Thanks Joe

First, I have a 1973 Plymouth Road Runner. I am not saying I will, but am wondering how it would look with t-tops or a sun roof.

If it is an original 440 car don't do it. There were only 117 440/GTX option Runners made in 1973. Keep it original, that is were the value is.

What are Belt Moldings on a 1969 Road Runner?

I may be wrong, but I don't believe '69s had belt moldings. These are the thin strips that go the length of the sides that protect the body form "parking lot" dings.


Belt mouldings run on top of the doors and continue onto the quarter panel to the end of the side window. Two seperate pieces.

July 26, 2005

Just installed a new 440 in my 1969 Road Runner. I have a "ticking noise", almost like a pushrod, coming from the top of the timing chain cover. I zero'd in on this location using a stethoscope. This noise rises and falls with rpm. I thought it might be the fuel pump, so I replace it, no change. Any help would be appreciated. Randy

What I ended up finding out was that it was the pushrod that runs the fuel pump that was making the noise.
Thanks,
Randy

I have a 1969 Road Runner that needs a total restore, did Plymouth have an assembly manual, if so where do I go to get one? I asked Year One, they said yes they have one, and sent me a Service Manual, this is not what I am looking for. I need a manual that shows how the car goes back together.

You can get a shop manual and that will tell you how to disassemble and assemble the different parts of the car, but I'm not sure you are going to find a "how to" manual on putting it all back together once it is disassembled. The way the really good restoration shops do it is to take pictures of everything BEFORE you start disassembly, take more pictures DURING disassembly, bag and tag EVERYTHING you take off the car (put it in plastic bags and label on the bag what the part is and where it came from.) Clean everything up and then decide what can be restored and what needs to be replaced. Its a lot of work but if you pay attention to detail you can get it all back together just fine.

July 26, 2005

I have a 1973 Road Runner in which I just had painted. I have all new emblems, and stickers. I don't know exactly where they go. I have a rough idea, but I want to be a 100% sure. I tried calling Hemming nobody there could help. I forgot to mention 1973 Road Runner has a vinyl top. I also checked with Phoenix Graphics to no help. Any help would be appreciated. Bob

July 25, 2005

I have a new battery, the starter is good, the ignition relay switch is good, and a new distributor cap, and solenoid. The car fired up just fine Saturday morning, but after sitting for one hour, there is no "click" or turnover attempts by the starter. I'm stumped.

July 24, 2005

Where on the 440 engine can I find what year it's from? Is a replacement engine in a 1973 Road Runner I want to buy, but owner doesn't know the year his engine is from? And, if I'm correct are the 440 engines after 1970 equiped with less horsepower than before?

The year is on the side of the block, about 1-2" high. Also on the pad in front of the intake manifold, where the 440 is stamped, there should be a letter before the 440. For example, a 1970 440 would have a capital F.

Hi, I'm getting a crate motor from MOPAR part # p4510851 its a 360ci engine with 380 (give or take) horsepower. Now my question is I need a tranny, I'm looking at a 727 4 speed automatic. The car currently has a sluggish 318 with a 3 speed 904 trany. Now I know I'll have to change it from the column to the floor. I need to know all the info that goes into swaping a tranny. Thanks

I am the previous owner of a matching number 1970 Plymouth Road Runner; 383/335 4 speed, bucket seat, air grabber car. Originally green with a vinyl top, repainted black with Cragar SS wheels. I sold the car to an individual in Trenton/Lawrenceville NJ, back in 1978/1979. I am trying to locate the car to possibly purchase. Have pictures of car from High School yearbook. Great sentimental value. Any leads on this would be greatly appreciated! 704-383-1704. I am trying to find the VIN number from old insurance cards, but have not found them yet.

I know some states DMV can help with title searches. You might try yours.

1968 Plymouth Road Runner 383: I have a stalling problem when the engine is warm. The car will not restart til after 1-2 hours. The problem is very intermident. One time the car had been run, sat for 1 hour and then started, but stalled about five minutes later?

Car has a Accel super coil
Mopar orange electronic ignition box
New wires and plugs

I'm assuming vapor lock, but I'm not for sure. When it happens next I'm going to check for spark at the coil to see if the problem is in the ignition system. When I operate the throttle, I see gas squirting into the carb? Any help or advice would be greatly appreciated!

I would check the fuel line and fuel pump.


At one time I had a car that had a weak coil and when it got hot it wouldnt fire , when it cooled down it would fire again good luck

As one of the last aspects of my RR restoration I want to use a hidden stereo system under the seat possibly or trunk mounted. RF handheld control so as not to compromise the original in-dash AM/FM. I have had some luck, but am concerned about quality. Any suggestions?

Using an RF modulator style CD or CD Changer will sacrifice sound quality. The signal is fed through your FM tuner. Unfortunately, tuners have poor frequency response and high signal to noise levels with poor stereo separation. Will it work. Yes and virtually all manufacturers make CD players that will connect in this way. What is a good alternative is to use a kind of "Y" box which might be hard to find. It's made by Denon and I remember most of the model number D?L-420. It allows two systems to operate on a common exterior amplifier. Mount the unit and an amp under your seats and you are in business with true CD sound!

Are there other locations I should be aware of before starting the sheetmetal repair/replacement work? Thank you.

My Dad ordered a 1968 RR from Carthage Chrysler/Plymouth, Cincinnati, OH late in 1967. Dad and Brother both have passed away and I have been trying to locate car for several years as it was sold to a friend of family in Cincy in 1977. I don't have a VIN as this would certainly make my search easier. ?? Is there any way to locate the specific cars Vin that went to a particular dealership as this one is no longer on the map. Subsequently, could the car VIN be further narrowed down by color combination/delivery date for that particular dealership? Our car was somewhat unusual in color/options: (Dark Forrest Green with Deluxe Wht vinyl interior and decor package. Unusual traits were the fact that it had both fender mounted turn signals and chrome rocker molding...have only seen 1 RR since then that had these options. Lastly, car had unusual hubcaps...not dog dish or style-steeled road wheels but a nice looking cap with Plymouth emblem in black 4-5" diameter circle with small rectangles surrounding center cap. Also believe that had some argent material similiar to what what used on grill.) It would certainly be nice to locate/restore in honor of my Dad and Brother. Thanks for any help anyone might provide.

Anyone know who carry's 22 inch radiators, all I can find is the 26?

First, check this website under the "For Sale" heading, I have seen several here. I believe YearOne still carries them. If they don't you may need to go online and search for one the hundreds of radiator shops that either carry or will make one for you. You can also go the route of contacting any of the racing radiator shops, give them your dimensions and let them build one for you. If you want to go the original route, contact places like Tony's Auto as they have lots of units. They may need to be recored but they will make a great unit. If you go with the original, I would suggest finding a 3 core unit (usually air condition) and have it recored. It has a lot of capacity and will cool anything stock and slightly modified unless you get really radical with the engine.

July 15, 2005

Any idea how many Road Runners/satellites and Chargers were made in 1974? It seems like there is more parts for the Chargers and fewer for the Plymouth... Thanks, Glenn

Hi. Does anyone know of a website that lists all of the codes on a build sheet, and what each one means, including all of the available options. For example, my build sheet says the paint is "JJ1", so what color is that? Thanks.

The paint code JJ1 is listed in the book I have as "Med. Gold Metallic." This code is listed as a 1968 exterior color. There are a few web sites out there that list some of the codes for doing the rest of your build sheet. Off the top of my head I don't know them to direct you there. We are currently compiling a list of all the codes we can, to put them on the RoadRunnerSite. Due to the number of codes we haven't yet posted the list as we'd like to be as complete as possible from the start.

Where is the water sending unit located on a 440 engine? Is it in the block or on the water pump? If it is on the water pump is it between the to heater house location or bolow where the two heater hose's connect? Can some one send me a digital picture on the location?

The temperature sending unit is on the pump and in one of two places depending on the water pump housing you have. One location is on the top of the pump near the two heater hoses connections. It will have a single wire plugged into the top. The wire is normally covered with a heavy cloth type covering and I think the actual wire is dark blue. The second location is on the front of the pump, just to the right of the alternator. (facing the engine) and under the heater hose connections. If your car has the factory alternator bracket, there is normally a hole through the bracket to get to the temperature sending unit. It too will have a single wire plugged into the end.

I own a 1968 Road Runner "383" I currently have redline tires G70x14 on the car and would like to replace them (keep them stored as orginal tires) with a 15 inch tire and deep dish mags. What rims can I replace them with? Is there a conversion from G70x14 to a rim that will work on the car? Thank you

I also have a '69 runner and went from 225-70R/14 tires on 5.5" steel rims to Magnum 500 steel wheels in the following sizes:
15"x8" rear w/4.5" backspace mounted with 275-60R/15 B.F. Goodrich Radial T/A tires.
15"x7" front w/4.5" backspacing mounted with 225-70R/15 B.F. Goodrich Radial T/A tires.

The 2 different tire sizes are the same height You can run any 8" wheel on the rear with the standard 4.5" backspacing easily and the 275-60R15 tires fit with about an inch to spare to the fender lip. The 275-60R/15's are listed at 11.4" wide and look great on the rear of the car. You could probably go to a 295/60R/15 or even a 255-50R/15 but you would have to be careful. There is a lot of room in the fenderwell but don't go too crazy!

July 4, 2005

I cannot get my blinkers to work, new flasher, when you turn them on no lights in dash, fuse good and the hazards work. Any help would be appreciated. Don't know what else to do.

Hard to troubleshoot on line. The only thing I can suggest is to take a shop manual and multimeter and check the wiring in the steering column. If you have any doubt about the steering column wiring, get a new turn signal switch which has new wiring connected (most restoration houses such as YearOne have them) and install. This will give you new wiring to your under-dash connector. Make sure all the contacts are clean and tight. This will eliminate the steering column as a source of trouble. If the new switch doesn't correct the problem, wire checking the underdash harness is about your only hope to find the problem.

July 4, 2005

Hi. I have seen 68 Road Runners that have trim across the trunk, and have seen others that don't. Does anyone know what the difference is? Is either one any more rare? Also, my 68 has a reverb unit in the dash, right under the radio. Is this a factory item, or did someone install it aftermarket? Thanks in advance.

The trunk bright work was a part of the Road Runner Decor Group, which included deluxe interior, and deluxe steering wheel. No reverb unit was offered by the factory, in fact only the only radios offered were an AM or AM with 8 Track Tape.

Where on the engine can I check to see if a 1971 Road Runner is a numbers matching car? It is a 383, and when I do find the number on the engine what am I matching it with? Thank you

Its just above the oil pan on the pass side, the first 5 digits of the VIN.

Check your motor mounts, drive line and u-joints


check your leaf spring bushings also

July 2, 2005

I have a 1968 Road Runner that has a constant intermittent vibration. I have had to change two tail shaft housings in the last two years. I believe it is coming from the drive shaft or the rear end. Where do you think I should look first?

Here are a few ideas to try and isolate the problem. Drive down the road and when the vibration occurs, take the car out of gear so the engine idles. Does the vibration go away? If it does, it is related to the engine/clutch/torque converter. If the vibration continues, the problem is probably drivetrain related. Make sure you don't have a broken motor mount or the rear transmission mount. Pull your driveshaft out of the card a take it to a shop that can check the straightness and balance of the shaft, I would then install two new u-joints. reinstall the shaft, make sue you seat the u-joint cups in the rearend yoke correctly and tighten the u-bolts to proper torque.

June 29, 2005

I have recently found the original build sheet for my 1967 Belvedere just wondering if anyone can help me decode it or point me in a direction to get info on how to do that? Also looking for a good parts supplier for these types of cars.

Business such as YearOne, Jim's Auto Parts, Totally Auto and Tony's Parts all have either new restoration pieces, NOS pieces or parts cars. Some offer mail-in restoration services for things such as grills, taillights, etc. You can also obtain several books on restorations from this website or from the companies listed above and others. Query the internet under "mopar restorations" or similar searches. There is a lot of information out there. You can also contact Galen Govier at http://www.gvgovier.com. He is the expert of experts when it comes to information on Mopars.

June 24, 2005

I have a '72 Road Runner and I was wondering where I could look up specific production numbers on my car. Such as how many 340's came with a pistol grip 4 speed. How many came with a full black vinyl roof. Thanks, Dennis

For you and everyone else who is looking for production numbers, etc please contact Galen Govier http://www.gvgovier.com/ He has a lot of info and may be able to help. He may charge you for some of the info but that is only fair since his sole means of income is helping Mopar enthusiasts with questions about their cars. Some questions just can't be answered (like how many Limelight Road Runners were equipped with this or that options, etc) because there were 4 production facilities and all the records were not kept in one central location. Good luck with your inquiry.


There are a number of restoration books available from places like YearOne and Jim's Auto Parts that can provide you with a wealth of knowledge. I would get on their websites and locate the books that apply to your Runner.

Someone that I went to school with is selling his '71 RR. He rolled it on the way to school one day. The fenders have a few small dents and the roof is caved in a little. It has a 3 speed and a Vinyl Top with the factory sunroof (which I heard was pretty rare). The engine in it is a '69 383. The damage to the body panels doesn't look bad and there is no bondo or rust (other than surface rust forming where the scratches are). The back end doesn't sag at all, due to new air shocks. The kid said that the guy he bought it from wanted $13,500 for it (cherry condition). He ended up getting it for $8000. He's trying to sell it for $4000 and I was wondering if that was a good price or not. He said it has over 400 horsepower. Also if I did buy it, how hard would it be to bump out the vinyl top? The dents are, in the worst spots, about 2 inches deep with no creases. I think it may be a chore with the sunroof being there.

June 22, 2005

My question is ...I have a 1972 Road Runner with a 400 in it. It has the hurst shifter with the stripes going over both sides of the hood. This is the only place the stripes are. I am looking for an orginial pictur of this machine so that it can be restored. Any info about this car would help me greatly. I can't seem to find anything on this car. PLEASE HELP!!!

if you are looking for an original pic of your car I would suggest contacting one of the previous owners. You have provided no details about this car so it is highly unlikely anyone here will be able to help you with an "original" picture of your particular car. Now if you just want to see a pic of a 1972 Road Runner there are numerous sources you can find including Year One (www.yearone.com). Year One's catalog has a lot of pics in it and they also sell books which probably have what you are looking for. Or you could try your local bookstore. If they have no automotive books showing a 72 rr I'm sure you could order one. If you are looking for a pic of your particular car please be specific and provide details (color, VIN, state/city it was originally sold in, etc). Without specific details nobody can help you.

June 20, 2005

I have a 68 Road Runner that has a fender tag which only states PREP LINE on it. Has anyone ever heard of this? The car has no options other than the engine and 4 speed. I've spoken to many people and no one has ever heard of it.

June 20, 2005

I have a 69 Road Runner that the previous owner had dropped in a 400 block. I had the motor rebuilt last summer. Everything runs great until the engine is warmed up. Then the motor wants to choke and stall. It has been upgraded to electronic ignition. It appears to be starving for fuel, or some sort of vapor lock. Any suggestion?

I would check these items. Make sure your automatic choke PULLOFF chamber is working properly. You can put a piece of vacuum hose on the chamber and pull a vacuum on it to check operation and make sure the diaphragm is not ruptured. If it is OK, with the engine cold, pump the throttle one time to set the choke and then fire the engine. You should see the vacuum pulloff chamber open the choke butterfly on your carb about a 1/4 inch. This butterfly opening should increase as the engine warms up until it is completely vertical. Second, is the heat riser on your exhaust manifold operating correctly? This valve (on the passenger side exhaust manifold) sends exhaust gas through the intake manifold and under the carburetor to improve cold drivability and to warm up the choke so it will come off quicker. The heat riser should also open as the engine warms up to stop the exhaust gases from going under the carb. Next you may need to check the float level in the carb. If it is to high it may flood your engine, especially when it gets warm. Check your fuel pressure. If it is too low you may be starving the engine or creating a vapor lock condition. If it is to high the float needle and seat may not be able to hold the fuel pressure and will make the carb run very rich (flood). Make sure your gas lines are not close to a heat source like an exhaust manifold. Also make sure the fuel filter is not getting hot depending on where it is. If it is behind the alternator, make sure it is not touching the block. Either one of these last two can cause vapor lock.

Where is the VIN# stamped on a 1968 GTX 440 block?

I believe it's just above the oil pan on the passengers side.


The vin on a 1968 Mopar engine is on the top of the block behind the oil sending unit where the block meets the bell trans/bellhousing. It is a partial and hard to find at firstbut it is always there.

I have a 1970 Plymouth Road Runner. Originally a 383 now converted to a 440 Six Barrel. The origial radiator is a 22 inch, it of course is not cooling the new motor so I have bought a 26 inch. My question is: Is there a kit out there that I can use to attach the new radiator to the existing radiator support or is this strictly a custom job? The car is already done so I do not want to install the correct radiator support. Thanks, Bill

I don't know of a kit to help your problem. If you have a 22 inch radiator support all the airflow you are going to have is what can flow through the 22" opening. I would have suggested getting a 22 inch 3 core radiator with a shroud (I have seen several on ebay under "383 mopar") and good thermostatic clutch fan. It would have cooled your engine combo just fine and you could have used your existing radiator support. Another option is to contact one of the many custom racing radiator people and order a 22" 3 or 4 core radiator to bolt in your car. If you tell them your engine and driving requirements, they can build you something to work. The price is usually not that bad. Final option is to find a 26 inch radiator support, get it painted to match your car. I am fairly sure they just bolt in.

Hello, I have a over-heating problem with my 68 383 Road Runner. Here is what I have done so far. Any help or suggestions about what to do next would be greatly appreciated!
- Visual inspection:
- When the car is warmed up and the thermostat is open, I have bubbles in the coolant. When the car is first started up and ran for a minute or so and then shutdown, there is no pressure buildup once the radiator cap is removed. I'm assuming not a cracked block/head.
- No antifreeze in the oil. Oil is clean.
- Once warmed up, no white smoke.
- The overheating is mainly seen on the temp gauge, the overflow leaks some antifreeze out, but it isn't steam or anything.
- Replaced the temp sending unit.
- Installed a 160 thermostat.
- Combustion leak test: I narrowed it down to one cylinder turning the fluid from blue to teal green, but not yellow, indicating a leak. I guess this indicates a small leak?
- Coolant pressure test: The system holds 15-17 psi fine for any amount of time. If I had a combustion leak, the pressure should drop?
- Compression test: All cylinders are within correct tolerances. 130 - 145 psi. So, all tests seem to indicate everything is OK, but I do have bubbles in the coolant (suspecting combustion leak) and the temp gauge sometimes pegs out at the high end and then comes back to about a quarter. I guess I have a small head gasket leak in that one cylinder due to the teal green combustion leak test results and bubbles in the coolant. My next step was to get a new temp gauge and see if that was my problem. Any idea where I can get a thermostat housing with a temp sensor hole large enough for the aftermarket temp gauges? Any suggestions on my approach or any insight would be appreciated!

Have you taken the radiator to a radiator shop to be flow tested? Maybe roddin it out would do the trick.


The best piece of mind you can have is to install a manual set of temp and oil pressure gauges. I was cruising Brice Road in my charger once, had just driven 3 hours with no problems. I was sitting in traffic, and looked at the factory temp gauge, and it was reading very hot. So I pulled off and shut the car off. I was expecting it to boil over, but it didn't. After checking everything and not finding anything, we figured it was the gauge. After getting home, I changed the gauge,sender, still read hot. I put a set of manual gauges in. It never goes over 180, unless I'm idling on a very hot day. And I don't have a shroud. And the manual oil gauge reads 85 psi, while the dash gauge never goes over 35.

Could a Regular Road Runner have been ordered w/ White transverse trunk stripe V8W or is that the stripe on the hood (V8W)? Could the hood have been ordered w/ a white instead of black out stripe and what would the code be? Lastly, if the car isn't a Superbird why is A13 on the fender tag? I guess thats the BIG question.

June 16, 2005

Has anyone had experience with frame components from AutoRust Technicians? I have a numbers matching 68 Road Runner that is complete, but the frame is almost completely gone, and I'm getting ready to start doing something with it. The stuff from ART seems the best way to go. I'd appreciate any comments, opinions, suggestions, etc. Thanks.

Car is vibrating after 65 MPH, especially at deceleration. Sounds like a U-joint to me. The guy at parts store said I need to know the yolk size. I didn't know there was more than one size. How do I tell? I think I have standard gears because it's a D21 manual with no special gear codes. It's an original 1969 383 car. Thanks.

There are 2 yoke sizes:
Small: 7260
Large: 7290
Your car will have the larger 7290 yoke.


If I am not mistaken, the front drive shaft yoke on the small automatics and 3 speed transmissions had 25 splines. The big 727 auto and the 4 speeds used a 28 spine front yoke.


if the vibrartion feels like it is comming up through the shifter - you may have a worn crank bushing. We had a bad shifter vibe problem and that was the cure for us.

Tranny problems. My 1969 Road Runner has a tf 727 second week of driving the car my tranny went. I was told it was the sprag and I would need a new case. Ok, so I located a new case, then the tranny shop told me I should put in a reverse manual valve body, I notice this is not out of the ordinary to do this. My 1st question is can you do this with the stock valve body? I was told you can't. My 2nd question is: I was told to go with a cheetah valve body. If anyone out there can give me some insight on these reverse valve bodys. I could sure use the info. Thank you, Joe.

No it cannot be done with a stock valve body. I do not know how radical your vehicle is, but I believe that reverse valve bodies are basically for racing purposes. If there isn't a problem with the existing, use it.

I am a newbie to the game and I just bought a 1969 Road Runner with the fuel tank removed. 383/727 auto transmission. The seller provided me with a tank/sending unit that appears to fit. Problem is the tank has two hose connectors sticking out of the tank and the sending unit has two more hose connectors. There are only two lines coming from the engine. Is this the right tank/sending unit and if so, what goes where? Any help would be appreciated.

I found a 70 Road Runner locally and am in the process of talking the owner into selling it. It has a 440 six pack in it with the air grabber hood. The owner told me it originally had a bench seat and console shift. Did any of the 440-6 cars come with a bench seat and column shift 727 torqueflite?

Without a doubt. I believe the column shift was standard equipment and the console with floor shift was optional. To verify check with Galen Govier (http://www.gvgovier.com/). If anyone knows he will.

June 11, 2005

Did Plymouth ever put a 440 six pack in a 1972 Road Runner? If so how many came with this motor?

The 6 bbl option was advertised in 1971 as being available on 1972 models but was dropped due to smog regulations. In spite of this I believe there were 2 1972 Road Runners that made it out the factory doors equipped with the 6 bbl setup. Check with Galen Govier (http://www.gvgovier.com/) to verify these numbers.

Are the taillight extensions the same on a Road Runner and the GTX, I know the tail light bezels are different but don't know about the tail light extensions.

The fender extensions are the same.

The GTX extensions and bezels fit the Road Runner, and the car looks better with the deeper GTX units.

I have bought a Pro-Street 69 Belvedere, I am in the process of cloning the car into a 69 Road Runner, but I need some measurements off a real 69 RR to install the door emblems in the proper location. I need these following measurements, from the top of the door to the bottom of the emblem and from the side of the door (closest to the front fender) over to the where the emblem begins and last one is the space between the words "road" and "runner", thanks for any help on this matter.

In order to install long tube headers, I believe I will have to renove the steering column (from fire wall to the pump) in order to make room for the exaust chamber to drop down. Is it possible to remove only the section inside the engine cabin? Or, do I have to pull the column from the steering wheel? (69 Road Runner, stock 383 HP, power steering-maybe considered steering assist pump) Thanks

Before going that route I would be sure that removing the spark plugs, any studs that were used for the old exhaust manifolds and the driver side motor mount and carefully jacking the engine up will not give you the clearance to install the headers. I've put several sets of headers on all kinds of mopars and I've never had to remove the steering column. A couple of notes: if there are studs, some go into the cylinder head water jacket so you may want to drain the radiator first. Be sure to put some pipe sealant on any header bolts that go into the jacket. Also, be sure to support the engine at a place that jacking it up will not damage the oil pan. Depending on the headers, you may also need to drop some suspension pieces like the drag link from the steering box and pitman arm. If you do have to pull the steering column, the whole thing has to come out. From the steering box coupler to the steering wheel. It may be easier to get the column out of the car with the steering wheel off depending on your seats and space.

I have a 1967 GTX convert I got it with no motor, a buddy of mine just gave me a 440 hp police interceptor, that he pulled from a police car ten years ago. I'm trying to figure out the exact year of this motor, my buddy thinks its a 74, I've been to several sites, and they all say different stuff, the number on the "RB" plate on front of the motor reads, 7T 440 E HP, can anyone tell me the year? Thanks, Scotty V

Here's what your engine ID numbers mean
7T=1977 year model
440=440 cubic inch
E=cast crank shaft
H=4 barrel carb V8
P=premium fuel
If there is a second line it will be the month, day and sequence order the motor was made. The 1st number is the month, second number is the day and the third is the sequence number. It's a low smogger motor with probably 8.5 to 1 compression. You have a good motor there. With a few goodies added you can make some nice horse power and have fun runnin over Fords and Chevys. NOS is a real possibility for you.

Hello out there. I bought a remanufacured 440 1977 block 906 heads 1966-1972 steel crank 443/465 lift cam, msd distributor, elderbrock perfomer dual plane manifold, headers, 600 cfm perfomer carburater manual choke. I wonder what horse power it would make. I figure about 365 +15 haders about 380 gross hp? Question 2: I bought an oil pan the guy told me it was a stock oil pan measurements are 4 1/2 inches deep. I checked my oil pan in my car on the 383 it measured 5 1/2 inches deep. Does anyone know?

My Vitamin C Road Runner (K2 code) is also a Spring Special, code number A14. Does anyone know what a spring special is? Is that how it got the orange color or is it just the time of year it was built? Thanks, Roman

Acording to the sources I have checked the Vitamin C Orange was one of 18 colors available to anyone, anytime. The Spring Special was probably just a promotional offer at that time of year.

i have a 1971 Satellite, I'm replacing the ignition switch and lock cylinder...only problem is I can't get to them. i took of the steering wheel only to find the horn wiring and the gear display part of the column in the way. Can't get it off. Any suggestions would be great need help, have a Haynes manual only problem is that the take down and rebuild is based on an early 80's Dodge Diplomat. Thanks for any help, Gabe

I have an original 1969 Road Runner with 383, air grabber. Had the carb rebuilt, but they gave me an extra thick gasket for the intake manifold to carb. My old one was only about a 1/16" thick, but it was ruined taking it off. The new one looks more than a quarter inch thick and I don't want to slam the hood and break the air cleaner or hood. Does anyone know which gasket is correct? Thanks

Use a standard carb to manifold gasket and you should be just fine. You can get them at any parts store. The 1/4" gasket you described is a heat spacer to help keep the carb cooler but may not fit with you air grabber unit. What you can do to see if you have the clearance is get some modeling clay and put a 1" high x 1" or so wide piece of clay on top of your air cleaner at its highest point. Then shut the hood GENTLY and open it back up. The clay will be compressed. You can then measure the height of the clay to see if the 1/4" spacer will fit. If not - just go with a standard carb gasket and you will be fine.

What does the code RM21 on a 69 Road Runner with a 383 stick mean??

The R basically means that it is a B-Body Plymouth car. The M means it is a middle class priced car. Together they mean Road Runner as all middle price class Plymouths were Road Runners. The 21 means that it is a 2 Door Pillar Coupe model. The VIN only describes the model of the car and the size of the engine. The 383 should be either a G or H and would be the next character after the RM21. The VIN does not list any thing about the transmission or other options the car included at the time of manufacture. The fender tag, which can be found under the hood on the left front wheel well, and the build sheet, which may or may not be under the rear seat or carpet, list the options included at the time of manufacture. For a complete decoding of your VIN go to the RoadRunnerSite.com VIN Decoder.

I have recently completed a 72 Road Runner with a 340 4 barrel. I have several bugs to work out. I have a 22 inch 2 core rad that doesn't seem to be doing the job. After a 45 minute trip down the highway the temp gauge reached the boiling point. Would a 3 or 4 core rad remedy this or removing the thermostat altogether? Problem 2 involves an incorrect speedo reading of approx. 20 mph faster than acual speed. Thanks for any help.

Go with a 3 core radiator (for a/c equipped cars) and you should be fine. DO NOT remove the thermostat, instead go with a 160 degree unit. The thermostat is necessary in that it holds water in the radiator for cooling. Removing it allows the coolant to go through the radiator too quickly thereby actually RAISING the temp. I swapped a 440 into my 383 Road Runner years ago and the small 2 core radiator wasn't up to the task of cooling it so I went to the junkyard and got a bigger one - problem solved.

Get a Year One catalog, they have a chart in the speedometer section that tells you according to tire size, rear end ratio which speedo gear you need. This is probably why your speedo is off.

The tail light I need is for a 1972 Satellite. (It has been cloned into a Road Runner) So if anyone knows anyone who has one, let me know! Thanks Tom

I recently bought a 1969 Road Runner that has radial tires on it. I would prefer to put on the tires that orginially came from the factory. If my information is correct the size is F70/14, but I have not been able to find out what brand (Goodyear, Firestone?) they would have been. Does anyone know what is the correct brand? Thanks

Check with Coker Tire Company. They have period correct bias ply tires, white sidewall or redline. F70x14 is the correct size. They were produced with either Goodyear white sidewall or Firestone redline tires depending on whether or not optional tires were ordered. I believe the Firestone redline tires were standard. Check your build sheet codes (if you have the build sheet) to see which tires came on your car originally.

As I stated in my earlier all Road Runners came with Goodyear tires (not Firestone).

What year body style is the same as 1970? Are the 68, 69 the same as 1970? Also is the Satellite the same body style as the Road Runner?

1970 was a continuation of the 68-69 styling except that in 1970 the fenders were smoothed and had the 68-69 creases removed. The 1970 model also had a scoop effect on the rear quarter panel which as not on the 68-69. The grille and tail lights were also revised. The front and rear glass is the same and I suspect the side windows are too. In a way the 1970 model was a "seperate but equal" body style to the 68-69. If you go to a Mopar only car show you will see the 68-70 B-Body cars (Road Runner, Satellite, Belvedere, GTX, Coronet, Coronet R/T and SuperBee) all grouped together.

I recently replaced the gas tank in my 69 Road Runner with a brand new tank and fuel gauge (tank unit/sending unit). We took the utmost care in installing everything to avoid any after, instalation problems/headaches. However, now when the tank is full the gas guage inside the car reads that the tank is at 1/2 tank and and not a full tank as it should be. If anyone has any suggestions in regards to my problem your thoughts would be greatly appreciated before I end up removing the tank again. Thanks in advance! Regards, Dom

Does your temperature gauge read correctly? Both the temperature and fuel gauges run off of approx. 5 Volts from a small mechanical voltage regulator on the back of the gauge cluster. If it is bad, both gauges will read incorrectly. If your temperature gauge reads about 1/2 of what you think it should, your regulator may be bad. They are still available from Year one, Jim's Auto parts, etc.

I just purchased a 1970 Road Runner 383, and can't seem to locate the fender tags. Can you please tell me where they are located on the car? Also, if they are not on the car how do I go about getting a duplicate tag? If I am unable to get a duplicate tag, is there anyway to find out what the car initially came with?

The fender tags are located on the driver's side inner fender near the emissions sticker. Once you pop the hood you can't miss them if they are installed on the car. If they are not there the only way you can determine how your car was originally equipped is to check the build sheet - usually found under the back seat. If you don't have the fender tag or the build sheet you'll never know just what was installed on your car without completely disassembling it, which of course you don't want to do. If you have the build sheet you can have a new fender tag made. Just contact Galen Govier http://www.gvgovier.com/ for details on how to do that.

I just bought a 1969 Road Runner 383 the car is in very nice shape, but I am having a problem with getting the dash, dome, radio and map lights to work. Yes, I looked for the fuse box but there is none. Please let me know what I should be looking for. Thank you.

Usually the problem with the dash lights is with the dimmer switch on the dash. This is the round chrome wheel beside the headlight switch. as far as the fuse box, look inside your glove box, there should be a panel on the left side, held closed by two phillips screws. Sometimes it's easier to take the large screw out of the bottom of the dash and pull the fuse box down.

Where can I get a set of wiper arms for a 68 Road Runner. Also I am about to give up on the original AFB's on the hemi and replace them with "Edlebrocks"- a while back a magazine said which part #'s would be the best fit, does anybody have this information. Thanks, Ken

Check at your local bookstore for these magazines:
Mopar Muscle
Mopar Collector's Guide
Hemmings Motor News
Ask them to order them for you if they don't have them. They all contain ads from vendors with parts for sale. Also check on the web at www.moparts.com. You can also just do a web search for "mopar parts" and see what you come up with. Also try ebay Motors. There are a TON of parts vendors out there.

Hi all, I have a 1972 Road Runner 318 904 automatic and am missing the shifter knob off the console shifter. Any ideas where I can get another one? Also, does anyone know of an after market shifter that will fit in the console (willing to do some modification to console) Thanks, John

I have a 1969 Road Runner 4 speed 383. The original leafs are shot. The person I bought the car from put air shocks and the tall aluminum shackles on it. I see that Mopar has heavy duty leaf springs for sale. Has anyone used these and how where the results? Was the car to high? Did it ride ok? Help??? Thanks, Tom

Most of the replacement springs that can be purchased through Year One, Jim's Auto Parts, etc. are the heavy duty leaf springs that came on Mopars such as the Hemi and 440 cars. I installed a new set on my 1968 4-speed Runner and they brought it back to the original stance, maybe slightly higher in the rear but it looks really good. I also installed a set of the factory style shocks. I'm running BF Goodrich radials on 15" Magnum 500 wheels and they tend to help the ride somewhat. The car handles as well as a big block can and it rides firm but not uncomfortable. These cars were meant to go fast and in a straight line, very few creature comforts and they were not meant to stop or turn very well. That's why we love them so much....

I recently bought a 69 RR, origional 4 sp, with a early 70's mild cam 383. I've pulled the mild out, and ready to seat a fresh, .030 over 383.(fresh engine was previousely in front of an Auto trans (727). I am unclear how to identify and match up the "pilot bushing" to accept the 4 sp input shaft. How do properly define the cranks rear bushing???

Normally all the 383-440 forged cranks are drilled for the pilot bushing. If the engine came with an automatic behind it, normally the pilot bushing was not installed since the auto used the flex plate and converter. If the crank has the hole drilled in the end all you should need to do is obtain a new pilot bushing and tap it in place. Try it on the transmission input shaft first and check for a good fit. Be careful not to mushroom the bushing during installation so the transmission input shaft won't slide in.

You guys are amazing. Thanks for all the help with my first question. Now #2. First beautiful day, key in ignition, turn one grab of the starter and then nothing....lights work, radio works, tried jump no diff..cleaned batt and no go. Anything simple before I have it toto the shop? thanks jp

You didn't mention it but it could be your starter relay which is usually on the firewall just to the right (facing the engine) of the master cylinder. The relay controls the starter solenoid on the starter. If the relay is bad, it will not apply the starter solenoid with the 12 volts to energize it which in turn energizes the starter motor. It is easy to jumper the starter relay to see if it is bad but it is difficult to describe how to jumper it not having the relay in view. 2nd guess, make sure the battery lead is on the starter tight. If the relay and wiring are OK, you may need to check the starter.

I just had that problem. Try replacing the starter relay on the firewall.

We have a 70 Road Runner 2 Door hard top with a post the passenger window was broke out we have had miltiple windows ordered and NONE of them have worked and the have all cost over $600.00. Does any one have any way of finding out exactly witch window and where to fine one its been a year of searching and empty handed every time. Thanks to any one who can help.

You cannot have a hardtop with a post. If your car has a post it is a coupe (VIN starts with RM21). A hardtop does not have a post (VIN starts with RM23).

Hi guys. I have a 1970 Charger 500 that I'm getting ready to restore, and I have a question about the radio. Did the 70 Chargers come with both the knob radios and the thumbwheel radios? Mine has the knob radio, but I like the thumbwheel radio. Is it possible, and how much bother is it, to take out the knob radio and put in a thumbwheel version? Any help would be greatly appreciated. Thanks.

The 1968 & 1969 Chargers had the thumbwheels, the '70s had the knobs on either side. I BELIEVE that the thumbwheel radio should fit the '70 dash, but you will need the '69 radio face plate.

Just rebuilt my 69 383, 9.5 to 1 compression and put in purple shaft 284 deg 284 lift runs great, but now I only have 8 lbs of vacuum. Not enough to operate power brakes. Tried a vacuum can but not reliable enough in traffic. Any suggestions helpful. Change to manual? Is a new rod available. Hate to spend 2-3 hundred on a vac pump. Help me quick crusin seasons here.

It would be cheaper to buy another cam. Go with the Mopar Performance 282 Purple Shaft cam that has less overlap. There are two PS cams - one with long overlap and one with short overlap. They made the short overlap cam for guys like us with power brakes. I hat to recommend this but you can at least sell the cam you now have and make some cash back. Its a lot cheaper than a vacuum pump.

I just purchased a 1970 Road Runner with 383 ci 8 cyl 4 bbl High Performance with matching numbers and I need a book/websites that will tell the orginal parts & numbers the car should have. I would like to restore the car the best that I can.

If you have the build sheet or the fender tag you can find out just what was on your car. Contact Galen Govier http://www.gvgovier.com/ for one of his White Books which will tell you what your codes mean in the way of equipment in your car.

Except for the 440/6 pack, were the 383 and 426 Hemi the only options for the 1968-71 Road Runner? Was a 440 4 barrel engine ever an option? Thanks

The 440 4 barrel (375 hp) was standard on 1970 Road Runner Superbirds. It was not available on any other 1968 thru 1971 Road Runner.

Just purchased a redon 69 RR conv- really nice cosmetically but a few things...I am not a mechanic and that is why I bought the car all done so.... When the car is idling after driving, the oil lite comes on, then goes away as soon as you accelerate. Any reason to worry? I also get some smoking when starting but then it goes away. Also the temp gauge does not work? Where should I look for problem. I assume it worked as the car has been totally redone. Thanks for putting up with someone who can buy one of these great cars but really doesn't know that much about mechanics...but I love that deep growl. JP

The oil light may be coming on because the wire on the sending unit is loose, or the unit might need replaced. The best piece of mind you can have is to install a manual oil pressure and water temp gauge. When I rebuilt my 440, I installed a manual set of gauges. The factory electric gauge never shoover 30 psi, while the manual gauge pegged out at 80 psi. The smoke after you start the car is probably just because the valve seats in the heads are wore. This is very comwith 30+ year old cars. Nothing to worry about unless the smoke is excessive.

I have question on 383 is it possible to replace lifters without removing the heads or intake manifold? Is there a tool for this?

If you remove the valve covers, rocker arm assemblies and pushrods, you may be able to take a magnetic pickup wand or one of the spring loaded 3 finger style pickup wands and carefully pull the lifters out. Putting new ones in is the hard part. It would be MUCH simpler just to pull the valve covers, rocker arm assemblies, pushrods and the intake/valley pan off and replace the lifters. You can also checkout the cam for excessive wear during this time. Be sure to replace the valley tray with a new unit and put a small bead of silicon across the end pads (under the new gasket) and especially at the corners of the gasket near the holddown strips. This will help greatly in preventing leaks. Don't forget to put your new lifters in a pan of fresh engine oil before you install them. Also, be sure to put some engine assembly lube on the base of each lifter before installing. Both of these steps will help during startup after installation.

You do not need to remove the heads to remove the lifters and not long ago I removed and replaced 1 lifter using one of those cable type grabbing tools, but I think changing them all would be tedious. It is quite easy to remove and replace the intake manifold on a big block as you do not have to tinker with the distributor as you would on a smallblock.

I have a 1969 383 Road Runner with drum brakes. I want to put disc brakes on the fronts. Some tell me to use A body discs and change the proportioning valve. Some say to use Chrysler Cordoba Discs. I need some help and some advice. I also see all these other companies selling Disc kits for about $1,000. What is the difference? Will I get a lot better braking if I spend more? Please help!!!!!!!!!!!!!!!!!

I just got a 1969 Road Runner. How do I know if its a 1969 or a 1969 1/2? Whats the difference?

The 69 1/2 is the one with the six barrel carb set up on the 440. All other '69s would have a 383 or HEMI. You can check this by the engine code in your VIN#.

Apr 8, 2005

I have a 1968 Road Runner the VIN# is RM23H8A218059 and the trim tag doesn't have much on it. One of my questions is do these cars have more than one fender tag ever? This car is a 4spd car and I believe a 383 cid not sure according to VIN it says 383 4bbl. I have not received the car yet to check if there's more than one fender tag. From a photo at the best I can make out with the help of the party at the other end, verifies tag as such.

D- Do any of these numbers on this fender tag indicate 4-spd or posi,engine hp,dash cluster,shift light,bench seat or bucket, interior color,cloth or vynal, factory tach???
It sure would be a big help if you could shed some light on this car for me.
Thanks Mopar nut wanna be.

I'd have to look deeper into my books to translate all the codes, but the bottom line indicates 62 for the 383 4 bbl and the 3 means 4 Spd transmission. If you are a beginner with Mopars, I'd suggest you purchase the book "Charger, Road Runner & Super Bee Restoration Guide". You can do so through our online store at http://www.cafstore.com/moparpubs.html, which is affiliated with Amazon.com.

I have a 1972 Road Runner and need to breakdown the VIN and the fender codes, need to know where to find this info.

You can decode your VIN using RoadRunnerSite.com's VIN Decoder at:
http://www.roadrunnersite.com/vin/vinhome.php

We are working on adding a fender tag decoder, but there are many other web sites and books available with the codes. Many have found the book "Charger, Road Runner & Super Bee Restoration Guide" helpful for decoding fender tags and for other restoration information. You can purchase this through the RoadRunnerSite.com's store called HHStore at:

Hi, I am trying to decode a 70 Road Runner. I am interested in buying, it has V8W on the fender tag which I know means "Transverse stripe White", but the car has a dust trail on the side. This is supposedly a survivor car and it looks original. Have any of you guys seen a white transverse stripe on a 70 Road Runner? Thanx for your help.

The transverse tape stripe runs across the lower lip of the trunk lid, just above the tail lights. It was standard on all 1970 Road Runner Hardtops and Convertibles and available an option on the coupes with deluxe interior. The trail dust stripe run down the side of the car from the Road Runner on the front fender, to the scoop.

I have a 69 Road Runner with a 383. The headers that came with it touch or real close to 2 spark plugs and the starter. I want to get coated headers. What do you recomend and what size? I want headers that don't burn everthing up!!!! Let me know. Tom

The best headers you can buy for the money are by tti (tube technologies, inc.). They are expensive buggers but well worth the money, particularly in terms of ease of fit and quality of product. I'm running their chrome 1-7/8" headers on my 1969 383 4-speed Road Runner. They installed so easily my buddy and I couldn't believe it. We never even jacked the engine off the mounts, just put the car up on tall jack stands, turned the wheel to get the pitman arm (driver's side) and idler arm (pass. side) out of the way and up they went from the bottom in less than 2 minutes. I even had the exhaust studs in the heads but I did have to remove the spark plugs. Check them out at http://www.ttiexhaust.com/ They post prices, pics and everything there. I'm also running their 3" pipes and a set of 3" Magnaflow stainless mufflers (got them elsewhere) and everything just bolted right up in a snap. I didn't have to touch anything when bolting up the headers, either. I have a 4-speed with the 11" clutch setup and the headers cleared the bellhousing, z-bar linkage and everything. I did have to go with a mini-starter but I wanted to do that anyway. Trust me, I tried 2 sets of Hedman 1-3/4" headers that did not fit with any starter. Evidently they were made wrong according to the Hedman engineer I was consulting out there. I thought I'd try to save a few $$$ by going with cheaper headers. All I can say is "you get what you pay for." Pony up and do it right. You won't regret it.

I have a 1969 Road Runner. I would like to install a tilt column w/shifter. Does anyone know what if any other Mopar columns will do the trick? Thanks for the help. Joe

Tilt columns were offered on 1971 and up B-Body cars, you could check them for fit.

Mar 22, 2005

I have a 1971 Road Runner with a 383 and suffer what seems to be a vapor lock condition after I try and restart after 10 minutes or so. Any suggestions on how to cure this problem?

Vapor lock is simply liquid gas turning to a vapor state due to excessive heat. I would look at the fuel line routing from the tank to the carburetor. Make sure the main line is not close to exhaust heat. Under the hood, make sure the fuel lines are not close to the engine or exhaust manifolds. From the fuel pump, make sure the line is away from the engine block and heads. If you have the a fuel filter that is behind the alternator, make sure is has room around it and its not touching the block or head. If the lines are all ok, you may need to try a base gasket under your carb that has a layer of heat insulation material. If all else fails, you can wrap different sections of the fuel lines with aluminum foil (just for test purposes) and see if you can determine what section is vapor locking. Also make sure your fuel pump is operating correctly and it has the proper pressure output (at least 3-4 psi at carb). Hi-Po pumps are higher output. Another thought, make sure the gas tank is vented ok, if the car vapor locks, remove the fuel cap and try starting. If the tank gets hot with no vent the pump wont pull the fuel correctly. Another thought, if you are running factory exhaust manifolds, make sure the heat riser is not stuck closed forcing exhaust gases continually under your carb causing it to overheat.

I have 1968 383 hp engine 4 speed trans. Orignal engine I need to know if the crank is cast or steel. Does this make a diffrence replacing the engine?

Your crank is forged steel. If you replace it with a cast crank you will need to use the matching harmonic balancer that goes with it. The forged cranks are internally balanced and use a thinner balancer. the cast cranks are externally balanced and use a thicker balancer. Since it is a 4 speed car this is all you need to be concerned about. Automatics require a balanced flexplate but you don't need to worry about that.

When I was a kid I found a plastic Road Runner head on the road. It has Mopar part #1 3343513 465019 on it. I assume it goes on the Road Runner car somewhere. If anyone knows where it goes I would appreciate some imformation. Thanks Dana

It is from a 1971 Road Runner. It goes in the center of the grille on a 1971 Road Runner.

This is both an announcement and a question. The Mopar National at National Trails Raceway in Columbus, Ohio, August 12-14 will be paying tribute to the Plymouth Road Runner this year (www.moparnats.org). I was wondering if any of you fellow Road Runner owners were going to go to the 'Nats this year? If so I'd love to hook up with some of you and caravan on up. I'll be leaving from Orlando, FL and would love to meet up with some of you Georgia, Tennessee and Kentucky Road Runner owners if possible. It would be so awesome to be a part of a Road Runner/Superbird caravan. Let me know if this sounds like fun so we can try to coordinate a caravan. Thanks.

I have a 1968 Road Runner that I removed the brake backing plate from the upper and lower control arm. The problem I can't get it back on due to tension on the lower control arm. The shop manual makes no reference to this plate removal and installation. There is a reference about relieving tension on the torsion bar, but the bolt it says to turn counter clockwise doesn't move no matter how much I put to it. Any help out there.

Feb 16, 2005

Can anyone tell me where to check for the VIN stamp and or engine code on a 1973 Road Runner. It appears to have the original 440, but I need to be sure. Any help?

I don't know what all you are needing to find out, but the vin #'s are located on the left side of the dash and also on the driver side front fender under the hood.

Feb 15, 2005

I have a 1969 Plymouth Road Runner cloned 440 6PK. Originally it was a 383 and converted over 8 years ago. Unfortunately, the fender data plate has apparently fallen off. I have no idea where to go or how to get a replacement. There is no broadcast sheet that I can find. The VIN is good as well as the secondary VIN. Where can I get another replacement and how can I get information on what numbers go on the data plate? The vehicle was built in Los Angeles and originally was orange. It is a post car not a hard top. Can anyone help me?

Feb 15, 2005

I was just wondering how much a 1970 Road Runner with a 440, 33,000 origonal miles but it was rebuilt and only has 800 miles on the motor. The whole car is origonal. Everything is excellent and straight as could be. I was just wondering if you could give me a guess about how much one of you guys would think it would be worth. I have had a lot of people tell me at least $50,000. Thanks

I am restoring a 1968 Road Runner - 383 Hurst 4 Speed and I have the following question. I am restoring the leaf springs and need to paint them. The documentation says they were either silver [original metal] or black. I can find very little evidence of black paint on them but they haven't been touched since 1968. Can anyone with knowledge of 1968 Road Runners tell me the correct color to finish them? Thank you, Randy Hlavac

Feb 4, 2005

I know this might not be a Road Runner, but it is its cousin b-body car. I have a 1974 Dodge Charger and I've changed the battery, alternator, alternator regulator and the battery still won't charge up. When it is the car will turn on, but when I disconnect the battery it turns off. Took the alternator back to the store to have it checked and the supposedly it works fine. Do you have any idea what it could be would really appreciate if you could answer, really need to get my car running to show it off. Thanks.

Have you checked the regulater? Might be a bad wire in the harness. When you unhook the battery and it quits, something isn't charging. I'd try getting another harness. They're cheap in the boneyards.


If you look at the back of the alternator you will notice a fairly large black wire, larger than either of the other two. This is the wire that send current back to the battery. If you follow it backwards starting from the alternator, it should end up back at the stater switch located on the firewall. However, it may be tied in with other wires but I suspect that you will find it disconnected somewhere close to the firewall. CAREFUL. You can do some serious damage to your wiring harness if you hook it up wrong. I strongly suggest that you go out to EBAY and do a search on Dodge Charger. You will find several wiring diagrams for sale there. I suggest the colored ones. They are very well done and easy to follow.

I was looking for a Edelbrock AVS Thunder series for my 1969 Road Runner 383 4 speed. It has the purple shaft cam. 625 or 800 cfm? What do you think? Any info or feedback would be appreciated. Thanks, Tom

My experience with edelbrock and carter carburators in trying to get good performance has shown them lacking. I would have to recommend either Holley or De, 700 to 750 CFM.

I put an edelbrock 750 on my 440 rr. runs like a top. replaced the Holley. to much trouble with it.

Feb 2, 2005

Could anyone tell me what the dimensions and location of the stripes on a 1969 Plymouth Road Runner hood are? Appreciate your help. Don

If you look back through previous questions, I saw someone answer this correctly some months ago.

Jan 29, 2005

My cousin just bought a 1969 Road Runner and it is Q5 turquoise color car....I have never seen one this color before, can anyone tell me how to find out how many of these were this color????

There are no records of the number produced of a particular color combination. You just have to look at the ratio of current true Q5 cars to all the other colors. You don't see many, so they are more scarce than most other colors.

Jan 25, 2005

I have a 1969 Pillar car that has what I believe to be the decor interior. Can anyone tell me if this option had bucket seats? The car I bought has the interior pulled out and in boxes. The previous owner started to restore it, but never finished. Any info. on what the decor interiors options might have been would be greatly appreciated.

Without a fender tag, the bench seat came standard, but yes, the bucket seats were an option.

Jan 25, 2005

I know this probably isn't a good question but here it goes. Is there anyone located in FL or South FL that has a Road Runner or know of Road Runner groups down here? I own a 1973 Road Runner and would be great to find some other Road Runner guys down here. Dan

I live in Orlando FL. There are a lot of 'Runner around down here but no specific Road Runner clubs I know of, however there are tons of Mopar clubs in the state. I am a member of the Mighty Mopars of Orlando. We meet the second Saturday night of every month at Orlando Dodge from 6PM to 9 PM or so.

Hi. I'm writing a book on Chrysler f-bodies. If anyone has pics and/or stories about Volare-based Road Runners, I'd like to hear from you. If you have anything regarding Volares or Aspens of any sort (especially Taxicab use--having a tough time finding stuff) please let me know. Thanks.

Check your fender tag or broadcast sheet to see if either are listed. There is a possiblity anyone may have changed/added the trim on the car.

Jan 23, 2005

I have a 1973 Road Runner, and am wonmdering how rare it is cause I can't find even a pic any where. Well I'll tell you about it, its not that impressive. Has 360ci engine. White not restored yet. automatic. When done its going to be hemi green, with blue lines. Any help or comments. Plus a pic would be great.

There are several web sites that address the 73 Road Runners. Year One has a great website plus an excellent parts book for the "B" body Mopars. I would advise you to get some of the available restoration books and manuals and do some research before beginning turning the first bolt. I too had a 73 Runner, at the time I sold it I didn't know it was one of 117 440 GTX option Runners that were made that year. If I knew then what I know now....

Jan 22, 2005

I have a 1968 Road Runner with a 383 engine in it. I was recently taking off the right header pipe to the engine block and when I removed the 5th bolt that fastened the header to the engine, antifreeze came out of the hole? My question, is this normal and do some of these bolts protrude into the water jacket or is this indicative of a leak from the water jacket into exhaust manifold pipe. I would appreciate any help in this mystery?

Yes, some of the studs/bolts for the exhaust manifolds on the 383/440 heads go into the water jacket. Be sure to put some antisieze/sealent on the threads when it goes back together to prevent leaks.


This is normal, the water jackets are inside. Either coat the bolts with sealer, or, as I do, use studs to slide the headers on (of course, coat the studs with sealer also).

Jan 21, 2005

I have a 1975 Road Runner and I have been searching the web for production totals, but can't find any. I know it's around 7,700, but that's all I've been able to find. Mine has a factory sunroof and I would like to find some extra info. If anyone could help I would appreciate it. Thanks Mike

You have a one-year-only vehicle. 1974 was the last year the Road Runner was its own carline. in 1975 the Road Runner was an option package on the 2-door Fury line. The VIN should start with RM21. Production total was 7,183. for comparison, that year they made an additional 53,666 two-door Furys. This doesn't include the Dodge Coronets built that year. in 1976 the Road Runner became a package for the Volare line. I got this info from the "Standard Catalog of Chrysler, 1924-1990" by John Lee, 1997.

Jan 19, 2005

I have a 1968 Road Runner with the original 383 that I am restoring. My question is, this Road Runner has roll-up passenger windows, not the push out type. I have checked the VIN and tag and it is a Road Runner, how rare is this option? Thanks.

The roll up rear windows were a result of an additional model. The early 68 Road Runners were considered "coupes" or a "post" car with the tilt out rear windows (VIN begins RM21). Plymouth later added the "hardtop" model that had the roll up rear windows that resulted in the post being removed allowing the entire front/rear window area to be open (VIN begins RM23). I believe you could order either model through 68. I don't have the exact number with me but in 68 there were something like 20-30K coupes and about 15K hardtops sold. There are a lot of websites that can provide data such as this. One of the best is "mymopar.com". I am also completing a restoration of my 68 Runner. There are several books from companies such as YearOne and Jim's Auto Parts (and many more) that specialize in Mopars. They have several restoration books on the "B" body Mopars that contain a wealth of knowledge on just about any part of your project. I would strongly recommend getting these books and studying them before you get too involved in your project. They all have websites with their catalogs on-line for viewing and ordering.

According to my Dodge and Plymouth Red Book, Chrysler made 15,358 hardtops, 29,240 coupes for 1968.

Jan 14, 2005

I just picked up a 1970 Road Runner, and can't really figure out how rare the car actually is. It is a hard top, air grabber car, FJ5, bucket seat, black and white interior, 383 4 speed, with the oddest combo of a white vinyl top. Pretty loaded w/rear defrost, dual mirrors, complete trim package. Does anyone have any idea how many of these may exist with this odd interior and vinyl top combo? Also have a restoration project not yet started for sale. It is a 383, 4 speed, bench seat, California car. Needs restoration. Non matching 383HP, and 4 speed included. Jeremy @ 440-487-3885

Have a 1969 Road Runner, looking for disc brake conversion. Can you help me? Built up motor, 383 up to 404 c.i. on the edge. Help me stop!

I changed to disc on my '70... Master Power Brakes 888-356-7291 or MPBRAKES.COM. The parts are Mopar stuff & the pads are available at any parts store when the wear out.

Jan 9, 2005

Hey folks. I have a 1969 Road Runner and a 1979 Road Runner. The 79 is new to me, and even though I know its a Volare, it's still one of 1122 with the Road Runner package, 360 4-barrel, a/c and nice leather seats. It will be a great, comfortable, driveable tagalong for the wife to drive to shows. I have no idea where to find parts or clubs which are dedicated or even include these rare notreallymusclecars. Can anyone help me? I just purchased the car on ebay, and its real cherry, very nice surprise as the Volares famously rot in bad places. This one is so stock and clean I really want to do things right. Thanks in advance for any help. :)

I have a 1969 Plymouth Sport Satellite Convert with a 318. The car has been sitting for 20 years and has been slowly restored.The master cylinder has just been re-built. The problem is....As soon as I start the car the brakes lock. When the engine is off the wheels turn. Any ideas what the problem could be ???? Thanks for your help folks...

Sounds like your car had power brakes, and maybe something is wrong with the booster. chaeck the vacum line.
