1967 Plymouth GTX 440, 426 Hemi

In 1967, Plymouth Division introduced what they labeled as a “gentleman’s” Muscle car, the Plymouth Belvedere GTX. It had great styling and performance different from the normal Belvedere, with its special grille, as well as mock hood scoops, chrome fuel cap and optional twin racing stripes. The GTX muscle car had superb handling thanks to standard six-leaf springs, heavy duty shocks, torsion bars and larger ball joints, the power steering though was believed to be too soft for the performance of the GTX Muscle car version. Plymouth did offer an optional disc brake that had no more advantage than the drum brakes. The interior was luxurious with embossed vinyl bucket seats.

To give the Plymouth GTX plenty of muscle to back up the performance image, Plymouth put in a 440cid V8, called “Super Commando 440” rated at 375 hp standard. This engine was tuned for more high performance RPM with a larger camshaft, valve train, a dual point distributor and a free-flowing exhaust and intake system. Mopars three-speed TorqueFlite automatic was standard, optional was a four speed manual transmission A Chrysler 426 Hemi rated at 425 hp was made optional in the Belvedere GTX for an additional $546, though only 720 GTX’s were sold with this engine. If you wanted more performance than a Hemi powered GTX, Plymouth offered what the labeled the R023 version (Belvederes were RH23 and GTX’s were RS23) of the Hemi GTX, called the “Super Stock” version. The R023 GTX was a stripped down model not marketed by Plymouth, only serious racers would even considered ordering it. Plymouth only built 55 of the R023 GTX’s, making them extremely rare.
