This extraordinary 1970 Plymouth GTX represents a rare and highly desirable example of American muscle car heritage. As one of a mere 350 units produced for the United States equipped with the potent 440 cubic inch 6 BBL V-8 engine and a 4-speed manual transmission, its exclusivity is undeniable. This particular GTX has been the subject of an extensive three-year custom ground-up build, with an estimated investment of $250,000, resulting in a vehicle that blends its original rarity with enhanced performance and stunning aesthetics.
Engine and Performance: The heart of this exceptional GTX is its original 440 cubic inch 6 BBL V-8 engine, a legendary Mopar powerhouse known for its formidable output. During the custom build, this engine was meticulously enhanced and now delivers a dyno-tested 508 horsepower and 550 lb-ft of torque, showcasing a significant increase over its factory rating. Upgrades include a new 6-barrel carburetor, an overbore of 0.040-inch, Eagle connecting rods, Edelbrock heads and fuel pump, Mopar electronic ignition, and a roller cam and rockers. Cooling is managed by a Be Cool radiator with a custom shroud and SPAL electric fans, while a billet serpentine belt system ensures efficient operation of engine accessories. Jet-Hot coated TTi headers and a 2.5-inch Flowmaster exhaust system facilitate optimal breathing and a thrilling exhaust note. The original 4-speed manual transmission, featuring a Hurst pistol-grip shifter, provides an engaging and direct connection to the engine’s power. A Centerforce dual-friction clutch assembly and flywheel, along with a Lakewood scatter-shield, ensure reliable power transfer. The robust Moser 9-inch rear end with 3.55 gears and a Traction-Lok differential further enhance the car’s performance and traction.
Exterior Design: The exterior of this GTX is finished in a custom House of Kolor Green paint, a vibrant and eye-catching hue that is further accentuated by subtle ghost striping on the Air Grabber hood scoop. New sheet metal was used from the firewall back during the build, ensuring a pristine foundation for the stunning paint finish. Details such as smoked tinted glass, replated chrome bumpers and trim, billet gas-charged hood hinges, and a rear spoiler contribute to the car’s aggressive yet refined appearance. The car rides on Raceline wheels fitted with Nitto tires, providing a modern touch and enhanced grip.
Interior and Technology: The interior has been redone in a stock-appearing Black, maintaining the classic muscle car aesthetic. However, subtle modern upgrades enhance the driving experience. A factory-appearing radio with Bluetooth capability allows for seamless integration of modern audio. Vintage Air provides climate control for่้ cruising, while Dakota Digital gauges offer precise and stylish instrumentation. New dash panels contribute to the refreshed interior, and Dynamat lining has been applied to the interior floors, firewall, doors, quarter-panels, and trunk, significantly reducing noise and vibration.
Chassis and Suspension: The custom build of this GTX extended beyond the engine and aesthetics to include significant upgrades to the chassis and suspension. An RKS Motorsports front and rear suspension system with coilovers provides modern handling and a refined ride. Power rack and pinion steering offers precise and responsive control. Full-length weld-in subframe connectors enhance the car’s rigidity, improving handling and reducing chassis flex. Wilwood power disc brakes ensure exceptional stopping power and increased safety.
