Plymouth GTXs

 
 

The Plymouth GTX (1968-1971)

 

 

The Plymouth GTX was introduced as the Belvedere GTX in 1967 by the Plymouth motor division to be a "gentleman's" muscle car. It was to be an exceptional blend of style and performance. What differed it from a normal Belvedere was its special grill and tail panel, as well as mock hood scoops, chrome "pit stop" gas cap and optional racing stripes. For the performance aspect of the vehicle, a superb suspension system was made standard. 
 
Standard too was Plymouth's massive 440 cubic inch (7.212 L) V8 nicknamed the "Super Commando 440." The motor was rated at 375 hp. Buyers in 1967 could fork over an extra $546 and replace the 440 with Chrysler's legendary 426 Hemi, which was rated at 425 hp. Only 720 people decided to do this. 
 

 

1968
 

In 1968 the Road Runner was introduced by Plymouth as a budget version of the Belvedere. There were minor changes made in the design of the Belevdere, which made it to both the Road Runner and the GTX. The Road Runner's base engine was the 383 cubic inch V8, while the 440 was still standard in the GTX. The TorqueFlite automatic transmission was the standard on the GTX, with it being a $206 option in the Road Runner. The GTX was offered in two models, the convertible and the 2-Door hardtop.   

 

 

1969

 
In 1969 the GTX's sales were hurt when the Road Runner was offered in a convertible model. The GTX received minor cosmetic changes as well as the introduction of the Air Grabber hood, which made the hood scoops fuctional and well as giving the ability to open and close them from the dashboard. 1969 also saw the introduction of the 440+6, referred to as the "440 Six Pack." In this configuration, the standard four barrel carb was replaced by three two barrel carbs. This produced an extra 15 hp, making the output of the 440+6 390 hp. The standard 440 V8 was still rated at 375 hp. 
 
 

1970

 
The 1970  GTX received some major redesign. The lines were made smoother, and a power bulge hood was introduced as well as non functional rear brake scoops. The convertible model was lost in 1970.The Air Grabber was brought back, but instead of being two scoops on the hood in 1969, it became one scoop located on the power bulge. The GTX was available with the standard 440, the 440+6 and the 426 Hemi. But because it was heavier, it was slower than the more popular Road Runner. 
 

 

1971

 
This was the final year for the GTX to be its own car. It was completely redesigned. The 440 was still available, but environmental restrictions lowered the output 5 hp to 370 total. Sales of the car were slow and that spelled the end of the GTX and the Hemi engine. 
 

 

1972 and Beyond

 
From 1972  to 1974  the GTX was no longer its own car, but rather an option package on the Road Runner.
