THIS VIPER-POWERED 1971 PLYMOUTH GTX IS PURE MOPAR MADNESS

Thanks To A Viper-Sourced V10 Engine

The early 1970’s were the absolute highpoint for American muscle cars. Whether it be a Ford, a Chevy or a Mopar, the company’s brightest and best came during this time period. One such example is the 1971 Plymouth GTX, which remains one of the most beautiful and sought after Mopars of all time. While the optional 426 Hemi was as potent as any factory motor at the time, it wasn’t quite enough for the team at Horsepower Northwest. Meet their Dodge Viper V10-powered Plymouth GTX-R project.

1971 marked the final year of the B-body Plymouth GTX as a standalone model, and they are a fairly rare car. That being said, it is possible that Horsepower Northwest have used a similar Mopar from the era, such as a slightly larger RoadRunner, as the basis of the build. However, it doesn’t appear that there will be much left over from the original car after the shop gets done with it.

We don’t have a lot of information on the build yet, however Horsepower Northwest’s Instagram does give us a few clues. The renderings show us what the car is going to look like, and a few build posts have given us a look at some of the parts. We know that the Viper V10 is already placed in the engine bay, and that the car will feature a 8.75 rear end. The shop is also partnered with Hotchkis Sport Suspension, so expect all new hardware front and rear. A set of massive Baer Brakes is also present to help slow the muscle car down.

It looks to us like this 1971 Plymouth GTX build is going for a mostly stock appearance, sans the massive wheels which hint at its pro-touring capabilities. The shop states that they build cars that are meant to be driven, and we are sure that the owner of this car can’t wait to try this 10-cylinder Mopar out on the drag strip.
