My understanding there were option packages, and a few years ago at the Mopar Nats. I saw a Roadrunner GTX convertable, no way for me to confirm it's originality, but that is the badging it had and I do have a pic somewhere, I'll see if I can locate it. The car was on display and roped off, so there was no way to get a pic of the vin or the fender tag.

But as far as individual differences, the GTX could be had with either a 440 or the hemi, these were the only engine options on the GTX models. The Roadrunner came with anything from a 318 to the hemi.

I know that the GTX could only be optioned with a 440 or a hemi.

The road runner was a lower class car with the 383 standard for `68-71,400 for `72 and 318 for `73-4.The GTX was an higher class car and came standard with the 440 from `67-71 and an option package on the road runner `72-74.The GTX also came with more options as standard equipment.

Your question is whats the difference between 69 Roadrunners and GTX's, so here goes:

69 Roadrunners were available with 3 motors...383 4 bbl, 440-6 bbl, and 426 hemi.
69 GTX's were available with 2 motors...440-4 bbl and 426 hemi.

GTX's were basicly fully dressed up B bodies, standard top line interiors with top level trim, exterior top level trim, unique GTX badging on the grille and trunk. Had a GTX specific trunk trim panel. GTX's and top of the line Sport satellites shared most of the trim. Could be had with an air grabber or not. The 4 speed cars would have a mandatory Dana 60 rear, 3.54 or 4.10 ratio. Automatics were standard with 8 3/4 rears, optional dana 60.

Roadrunners were stripped down Satellites with a standard 383 4 speed. Only engine option at the start of the model year was the hemi. In the spring of 69, the 440-6 lift off hood cars were brought out. They were a option package car (A-12) and had the fiberglass hood, standard Dana 60 rears, black 15 inch wheels with chrome lug nuts, and specific 440-6 call outs on the hood.

Starting in mid 68, you could dress up your roadrunner with interior and exterior option packages that would offer higher levels of trim. Standard roadrunners still had the low level interiors and minimal exterior level trim. Bench seats, column shifted automatic trans were the norm.

A small block Roadrunner was introduced in 1972 (340)...until then NO roadrunners had a small block in them. 1973 saw the first 318 available in the runner, and the elimination of the 440-4 speed combination.

72 was the first year the GTX and Roadrunner was a combined model. The GTX became an option package on the Roadrunner. It got you the 440 engine. NO roadrunners were available with a 440-4 bbl without the GTX option. There were a few cars that snuck out of the factory in the 72 model year with the 440-6, but the top dog drivetrain that was available was the 440-4 bbl with 4 speed and 3.54 dana 60. After 72, only automatics were allowed with 440's.

  Thats it!

so basically GTX for rich guys who wanna look good and go fast with 'creature comforts'

RR for younger guys with little income who can only afford a stripped-down muscle car, and still wanna spank any Chev that costs 4 times what their MoPar did!

That was the idea.

I agree with all that hemi71 says with the exception of a small block being offered in 71....340 WAS offered in a 1971 Roadrunner as a H code....

You are right ....hit a 2 instead of a 1...340's were first offered in 71

[71GTX]

The weights on the cars should be virtually the same with the exception of handling packages....Dana, anti-sway bars, etc....

[1970RTSE]

The basic difference is the level in trim on the Plymouth hierchy.  The GTX was top dog in both trim and power.  The road runner was actually in the middle.  The base Belvedere was the lowest.  The Satellite was about equal in trim, though not power compared to the road runner.  Sport Sat was a high trim version and could be had with the same 383 as the Road Runner (rated 5hp less due to air cleaner).  The Sport Satellites with the 383/4 speed are quite rare. 

A post car road runner is a little lighter than a GTX.  GTXs only came as a hardtop (no post between the door and 1/4 windows).  The GTX has been refered to as the Banker's muscle car.
