1967 Plymouth Belvedere GTX: Plymouth’s Fastest Way To Win You Over

Introduced in 1967 as an optional package on the Belvedere model line, the Plymouth GTX quickly made a name for itself in the automotive world. Available in both convertible and hardtop configurations, the GTX was a stunning two-door vehicle that seamlessly combined style and performance. Boasting a range of pre-installed performance options, it was a true force to be reckoned with.

Underneath its sleek exterior, the GTX featured a meticulously engineered suspension system. Leaf springs, modified shocks, ball joints, and torsion bars worked in harmony to deliver exceptional handling and control. Powering this beast was a formidable 440 cubic-inch eight-cylinder engine known as the Super Commando 440, generating an impressive 375 horsepower. For those seeking even greater power, an optional 426 cubic-inch Hemi engine was available, cranking the horsepower up to an astounding 425. However, this optional upgrade came at an additional cost of just over $540, resulting in a mere 720 buyers opting for the Hemi engine. As for the transmission, a three-speed automatic came as standard, but drivers had the option to swap it out for a four-speed manual gearbox.

For those seeking pure performance on the drag strip, Plymouth offered a limited edition Super Stock R023 version of the GTX. Built with the intention of dominating the racing circuit, this version came equipped with the Hemi engine and shed unnecessary weight by removing non-essential features like the heater, radio, and carpet. Only 55 examples of this stripped-down beast were ever produced. The 440 engine, on the other hand, offered a versatile driving experience suitable for both street and track, with less of the tire-spin issues faced by the Hemi.

In 1968, the GTX received both aesthetic and mechanical updates. The taillights and grille underwent revision, and a new hood design replaced the previous one. Disc brakes were added to the front, while the suspension was modified and wider tires were fitted. Additionally, a limited-slip differential was incorporated. These changes brought the GTX in line with its economical yet performance-driven sibling, the Plymouth Road Runner. While the TorqueFlite automatic transmission was the standard offering, customers could opt for a four-speed manual gearbox at no additional cost. Interestingly, only 450 GTX models were ordered with the Hemi option, which required an extra $564 on top of the base price of $3355.

Moving on to 1969, the GTX underwent only minor modifications, primarily focused on the grille and taillights. Notably, new features such as the Hurst shifter, Air Grabber option, and various rear axle options were introduced. This year also saw the inclusion of three engine choices. The 440 cubic-inch engine’s single four-barrel carburetor was replaced with a three two-barrel carburetor setup, resulting in a power boost to 390 horsepower. This variant was dubbed the 440+6 and commanded a mere $120 premium over the standard 375 horsepower 440 cubic-inch engine. Only 209 buyers opted for the Hemi engine, which came with a higher price tag of $700. Additionally, 1969 marked the final year the GTX was offered as a convertible.

In 1970, the GTX underwent a restyling that accentuated its aggressive appearance with the addition of a hood scoop and a bulge in the hood. The standard engine remained the 440 cubic-inch eight-cylinder, while the 440+6 and 426 Hemi engines were optional upgrades. The 440+6 proved to be a popular choice, with 768 buyers embracing the enhanced performance. However, the Hemi engine was chosen by only 72 buyers. Sales for the GTX in 1970 were lackluster, with only 7,748 units produced. The presence of the more affordable and faster Plymouth Road Runner played a significant role in this decline. Consequently, Plymouth decided to produce the GTX for one final year in 1971. The styling received an update, with curvier lines and a shortened wheelbase, while a wider track was implemented to improve handling. The Air Grabber option was available, and the standard 440 cubic-inch engine produced five fewer horsepower than the previous year. Only 30 Hemi-powered GTX models were ordered, while the 440+6 engine, still offered, delivered 390 horsepower. With only 2,942 units sold, Plymouth made the decision to make the GTX an option on the Road Runner for 1972.
