Plymouth GTX

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"

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.

go to the library and get a chiltons repair manual for your car.

the GTX was the upscale satellite with more options as the roadrunner was just basically a cheap performance car as some of them had no radio, no carpeting and push out rear windows.

no, the scamp is not the same size car as a GTX and would never fit.

If the engine has been changed to one that is different than was installed by the factory it is no longer a numbers matching car.

The 1969 Daytona Charger is worth more because there were fewer built, I believe 501. While around 2502 Superbirds were built in 1970.
