1967 Plymouth GTX Convertible — 707 HP Hellcrate HEMI — Tremec 6-Speed — Dana 60
Offered for sale is an exceptional and extremely rare 1967 Plymouth GTX Convertible combining the pedigree of a genuine first-year GTX with a professionally upgraded modern high-performance drivetrain and chassis.
Only 680 GTX convertibles were produced for 1967, and according to the documentation accompanying this car, only 47 were produced in Turbine Bronze, making this an exceptionally uncommon example.
At the heart of the car is a 707-horsepower Mopar Hellcrate supercharged HEMI backed by a Tremec Magnum 6-speed manual transmission and Dana 60 rear axle. With approximately 1,200 miles on the build, this GTX combines classic Mopar styling and rarity with modern performance and drivability.

This car was built to be much more than a showpiece. The combination of the Hellcrate HEMI, 6-speed manual, Dana 60, upgraded suspension, modern braking and steering creates a GTX that can actually be driven and enjoyed while still having the presence expected from a high-level show car.
The Turbine Bronze exterior is particularly striking on the convertible body and gives the car an appearance that separates it from the more commonly seen muscle-car colors. With only 47 documented Turbine Bronze examples produced, the original color combination adds another level of distinction to an already rare GTX convertible.
Significant time and expense went into creating this GTX. Reproducing a build of this caliber today would require sourcing a genuine GTX convertible and completing the drivetrain, chassis, suspension, braking, cooling and cosmetic work—not to mention the time involved in bringing the entire package together.
The result is an opportunity to purchase a completed, sorted and documented 707-horsepower GTX convertible without spending years building one.
The car was also recognized at the 2026 Detroit Autorama, receiving 4th Place honors.
This GTX is ideal for the collector who wants something beyond a conventional restoration: the rarity and unmistakable appearance of a classic Mopar combined with the performance, drivability and excitement of a modern 707 HP supercharged HEMI.
Located in Rochester, Michigan.
