Executive Decision

The 1967 Plymouth GTX has been called many things: The Gentleman's Muscle car. The Executive Hot Rod. And, for you Sox & Martin fans, "The Boss". Whatever it's called, the 67 GTX was muscle wrapped in refinement. Its sculpted sheet metal, featuring chiseled lines inside and out, along with tastefully applied trim and call outs made the 67 GTX something to see, while its standard big block power, made it something a lot of people saw from behind. It was an iron fist in a velvet glove. It was something special back then and it still is today. Such a beautiful and legendary car, deserves respect and, while we're at it, more horsepower.

The gorgeous GTX you see here, came to us looking pristine and perfect; our job was to pack in more power. Which we did, with one of our 512, 400-based stroker crate engines. For the specs on this brutish B-series big block, click here, but we think the spec you'll find most interesting now is the more than 640 horsepower and 670 lb.-ft of torque this engine made...all below 6000rpm. These numbers beat our previously recorded dyno numbers with these engines, thanks in part to our new, PIE-exclusive, SUPERTUNE/MAXPORT440 heads, which we'll feature another time. To the basic package, we also performed a Sniper to Terminator ECU conversion, added a PIE-engineered intake system which consists of  an Edelbrock MPI intake, custom spec’d throttle body and injectors, billet fuel rails & brackets designed and CNC'd in-house.

Just as impressive as the power numbers, is the way this car drives. The ride was so smooth and comfortable, that if you close your eyes, you'd think you were riding in a new car. Well, except for that glorious, BB MOPAR rumble. Score one for "old tech". Whoever thinks torsion bars and leaf springs are archaic and should be replaced with a more modern suspension, needs to take ride in this car!

It was a treat working on the GTX. Watching it roar to life with more power and performance potential than ever, and helping carry on the GTX Legacy makes us feel good. But we do miss it being at the shop. Without a doubt, this 67 GTX is still something special.
