Plymouth GTX

you need to get it aligned to set the height as it takes a special tool to get it set right and there is no specs on the back of the car, as long as you have good rear springs the car is set in the back.

a satellite is your lower model car with smaller engines and transmissions and rearends compared to a gtx which was top dog in the Plymouth b bodie line in 69 gtx had 440 or the awesome 426 hemi heavy duty 727 transmission or 883 4 spd and the Dana 60 rearend plus heavy duty suspension all put in a loaded interior and exterior package.

5-lug, 4 1/2 " bolt spacing.

none, either it was a GTX or a roadrunner.

Not so, 79 is the accepted number of "Road Runner GTX"s produced in the model year 1974. Any 72-74' Road Runner ordered with the 440HP engine was officially named a "Road Runner GTX" having both name plates.

When a 1972-1974 Roadrunner was upgraded to the 440ci engine, it became a Roadrunner/GTX. The Dodge/Plymouth Red Book pocket guides lists 79 RR/GTXs produced in 1974. This is thought to be too low. The White Books produced by Mopar expert Galen Govier lists the production of 1974 RR/GTXs as 386. This is the current accepted production number.

Yes, I know. But he has amassed a great deal of documentation and data. I wish I had the foresight to do that.

about 1,800 RPM.

basically it had a heavier duty suspension and bigger brakes and the 440 engine with dual exhaust, it was an upscale satellite with better interior and more ginger bread on the outside of the car.

well this depends if you want to keep the as close as original such as date codes matching your cars numbers , if that's the case then your job got a lot harder. if you want to put in a replacement engine then decide what size you want if your car is a true gtx it came from the factory that year with 3 choices the 440 4 bbl the 440 6 pack or the 426 hemi check the vin number the 5th digit in the vin will be a letter it will be either the letter R the letter U the letter V the other first 4 letters and numbers in the vin will be RS23 so anyway swapmeets sometimes turn up a good find junkyards might have one buried in it but they seem to be drying up on the older cars ,check the mopar webring online , or look for a old new yorker or imperial 60,s to 70,s the low deck 383 and 400 will also bolt into a big block car. they are out there you just got to dig a little.

Numbers range between 1920-1935 units

2942 1971 gtx's were made

The GTX came with a 440 CID 4bbl. 375 HP V-8. Only option was a 426 CID Hemi V-8 of 425 HP.

You should be able to tell by your vin # on the dash and the stamping on the block on the engine passenger side by the freeze plugs, the year should match.

Through 1971, the Plymouth Road Runner and GTX were separate models. Traditionally the VIN of the Road Runner started with RM23, and the GTX started with RS23. The base Road Runner came standard with a 383ci engine and a minimum of options. The GTX came standard with the 440ci engine, and was appointed with several standard options. The Road Runner was the cheap muscle car, and the GTX was the luxury muscle car.

This changed in 1972 as the GTX was dropped as a stand alone model and the 400ci engine became standard for the Road Runner. If you ordered a Road Runner with the one of two 440ci engine options that year, the model became a Road Runner GTX, included additional badging as such. There were 672 Road Runner GTXs produced in 1972. 219 were 4spd manuals, and 453 were automatics.

In 1973 and 74, the 318ci engine became standard in the Road Runner. Again, if you ordered the 440ci engine, your Road Runner became a Road Runner GTX. In 1973, 749 Road Runner GTXs were produced. And in 1974, 386 Road Runner GTXs were produced. All 1973/74s were automatics.

So the final answer is: There were 1,807 Road Runner GTXs produced from 1972 through 1974.

The model name for all "U" and "V" engine coded '72-74 RM23/RM21s is "Road Runner GTX". This official model name change is as described by existing Chrysler documentation;

"Road Runner will become a Road Runner GTX when it is ordered with either the 440 4-barrel or 440 6-barrel optional engines"

It is a 1969 Roadrunner, but you have to unlock with a cheat code

look on the passenger side on the side of the engine block .

get a chiltons repair manual from the library for 69 plymouth's and it should tell you.

Check E-bay or google

with the 440 or the hemi they were quick for the day.

They never made a road runner GTX, it's either a road runner or it's a GTX. That's a GTX

Grand Touring Xpress

The GTX appealed to a more upscale crowd, had upgraded trim and engine selections over the Road Runner, which appealed more to the budget-minded drag-racing crowd and was a much more stripped-down car by comparison.
