1974 Roadrunner GTX
07-16-2007, 10:18 PM
Hi to all. I am new to this forum. I am a Mopar nut and have been since my first Plymouth, a 1968 Roadrunner (wish I still had that one). I currently have a 72 Satellite Sebring Plus with a 318 that runs 8.80's in the 1/8. This car has been modified to a pretty nice street/strip car, but I do have all the original equipment that came with it in safe keeping. The only thing special about this car is that it is an I code (international delivery car). I also own a 1964 Chrysler New Yorker that is an original 57,000 mile car and is a sweet land yacht. My most recent purchase as of today is pair of Roadrunners. A 1973 Roadrunner and a 1974 Roadrunner GTX. I checked the vin's on both cars the 73 is RM21L and the 74 is RM23U. Can someone tell me what engine the L code is on the 73? The GTX is rough but most of the parts are there. The 73 should make a good donor for what is missing. With only 79 GTX's built in 74, I was wondering if anyone knows what kind of value these cars are holding. I bought it to restore to original and enjoy for many years to come. The 73 is a bucket seat center console car with the Ralley dash, are they worth anything? Well I will be checking in and asking many questions as this project goes along. Thanx in advance for any and all information.

First of all, if you have questions about your New Yorker, I'm your man.
Take another look at the VIN's for your two Roadrunners. The sixth digit (which you left out of your post) is the model year (3=1973; 4=1974). Of course, engine code is the fifth letter.
Your RM21L is a fixed quarter window coupe. Engine code L signified the 375 hp 440 in 1968 & 1969; the 330 hp 383 in 1970; the 275 hp 383 in 1971; and the 245 hp 360 hi-perf in 1974 & 1975. L was not used as an engine code in 1972 or 1973 (now you know why I'm confused).
Your RM23U is a two-door hardtop with rolling quarter windows. Engine code U signified the 440 hi-perf engine for 1970 through 1974. This is correct for the GTX, since the designation GTX meant 440 engine.
During model years 1968 through 1971, the Roadrunner and the GTX were separate models. You could order a Roadrunner with an optional 440 HP. The GTX came standard with the 440 HP. During those years, the interior appointments of the GTX were plusher than the RR. In 1974, at the end of the line for muscle cars, the RR and GTX were no longer separate models. The GTX designation was used only to differentiate the 440 HP equipped RR for the other RR's.

Thanx for the info. I was told that the Roadrunner was a 73, but as you said and I have found out from my many journeys on the net the L code 360 was a replacement for the 340 so this car must be a 74. I will be picking up the cars this weekend so I will verify the year then. Is the GTX in fact a 1 of 79 car? This seems to be the number that shows up for the U code cars. As far as the New Yorker goes she runs and purrs like a kitten. I am getting ready to convert to electronic ignition and am thinking about the Petronix kit to keep it hidden and thus keep the stock appearance. Other than an Edelbrock 600 performer she is bone stock. Again thanx for the info and if you know any numbers on the GTX I would definetly like to hear them and know where you got them.

Well you own one... and I own two, that doesn't leave too many around. I looked on NADA and they ranger anywhere from 16-30k But I'm guessing one that's perfect can pull in much more $$$

I would love to see some pics of yours. Mine has been a long time coming but it is finally coming home from the fab shop this weekend. The story is a long one on these 2 cars. The GTX was in worse shape than originally thought but the Roadrunner was in better shape so the Roadrunner has donated most of its panels and parts to the GTX (good thing I bought both of them). If all goes well it will be painted this summer. During the long wait for body work, no bondo or glass, all metal, I collected everything I will need to put it back together. One very good thing did show up once I had the tags decoded. Both cars came off the same assembly line 1 day apart, Dec 10 and 11, 1973. So all the body parts we used from the runner will be date coded correct for the GTX (assuming they were still stamping dates in 74). So with a little luck and a lot more money..lol, she should be ready to roll this time next year or sooner if the Great AA starts up OT anytime soon. I will be changing one thing from original on the GTX restoration, she will be getting AC (original non AC car), the runner was a factory AC car and has everything I need to put in the GTX. Hey when you live in Texas and plan to drive anything down here you better have AC..lol. Other than that she will be exactly as she came off the line. Also the runner has the same interior code as the GTX so I now know how to put it back to original. Will start posting more as we finally get this thing going.
