The 1967 Plymouth GTX holds a special place in muscle car history as the first year of this distinct and powerful model within Plymouth’s B-body lineup. Known for its aggressive styling cues, including a unique hood with twin bulges and a prominent “440” emblem (even if the engine underneath wasn’t always that displacement), the GTX was positioned as a sophisticated yet potent performer. This particular 1967 GTX has been the recipient of a comprehensive frame-off custom build, a transformation that has enhanced its powertrain and chassis while carefully preserving much of its iconic original aesthetics. The result is a vehicle that captures the raw, chiseled look of the first-year GTX but offers its driver a significantly upgraded mechanical prowess for an optimal driving experience.
Potent Fuel-Injected 505 Stroker V8: In place of the original Super Commando engine, this 1967 GTX now boasts a formidable fuel-injected 505 cubic inch stroker V8 engine, producing an estimated 600 horsepower. This modern powerhouse features a FiTech 3×2 6-barrel fuel injection setup mounted on an aluminum intake manifold, ensuring precise fuel delivery and optimal performance. The engine is further enhanced with Indy aluminum cylinder heads for improved airflow, Doug’s ceramic-coated headers for efficient exhaust flow, a custom fuel tank with an in-tank pump for reliable fuel delivery, a CVF serpentine belt system for improved accessory drive, and an Entropy custom aluminum radiator equipped with dual electric fans to maintain optimal engine temperature even under demanding conditions. This upgraded engine provides a significant increase in power and responsiveness compared to the original factory offerings.
Tremec 5-Speed Manual Transmission and Upgraded Drivetrain: Behind the potent stroker V8 resides a Tremec 5-speed manual transmission, offering the driver a direct and engaging connection to the car’s performance. This modern 5-speed provides both spirited acceleration and comfortable highway cruising capabilities. The power is then routed to a Moser limited-slip differential with a performance-oriented 3.73 gear ratio, ensuring optimal traction and efficient transfer of power to the rear wheels. A fresh wiring harness was also installed during the build, ensuring reliable electrical operation throughout the vehicle.
Enhanced Chassis and Suspension: The underpinnings of this 1967 GTX have been significantly upgraded to provide modern handling and ride quality. An AlterKtion front clip has been installed, allowing for the incorporation of power rack-and-pinion steering, which offers more precise and responsive control compared to the original steering system. The suspension system features adjustable coilovers both front and rear, allowing for fine-tuning of the ride and handling characteristics to suit the driver’s preferences. A 4-link rear suspension setup further enhances stability and improves traction, especially under hard acceleration.
Wilwood Big Disc Brakes for Superior Stopping Power: To match its enhanced performance capabilities, this GTX is equipped with Wilwood big disc brakes on all four corners. The front features 6-piston calipers, while the rear utilizes 4-piston calipers, all working in conjunction with drilled and slotted rotors for superior stopping power and heat dissipation. A Wilwood master cylinder ensures optimal brake system performance and responsiveness, providing the driver with confidence-inspiring braking capabilities.
Custom Interior with Modern Amenities: The custom interior of this 1967 GTX retains the classic bucket seats and factory-style console, complete with an auxiliary tachometer and a white ball-knob shift handle, preserving the original muscle car feel. However, modern amenities have been seamlessly integrated, including a Vintage Air climate control system with a custom control panel for comfortable driving in any weather. A Flaming River tilt steering column, topped with a stylish Budnik wheel, provides added comfort and adjustability for the driver. For entertainment, a Custom Retro Sound stereo outfit with Bluetooth connectivity has been installed, blending classic aesthetics with modern technology.
Striking Exterior and Custom Wheels: The exterior of this GTX is finished in a rich House of Kolor base/clear coat black paint, giving it a deep and lustrous shine. The car retains its GTX model identification and lower rocker trim, staying true to its original appearance. A flip-open gas filler cap adds a touch of classic styling. Modern custom Budnik Shotgun G Series wheels, sized 19×8 in the front and a wide 20×12 in the rear and wrapped in low-profile tires, give the car an aggressive stance and a contemporary flair. The lowered ride further enhances its sleek and powerful presence.
