The 1970 Ford Mustang Boss 429 Fastback is widely regarded as the ultimate expression of Ford’s muscle car ambition, a vehicle born from the necessity to homologate the massive 429 engine for NASCAR competition. This specific example, KK No. 2275, is a profound rarity in the collector world, being one of only nine produced in the striking combination of Grabber Green over a White interior. With the odometer showing just 4,898 miles, this highly original survivor retains its factory drivetrain and documented history. Crossing the block at Indy 2026, it offers a rare opportunity to acquire one of only five known surviving examples in this specific color configuration.
Grabber Green Vibrancy and Magnum 500 Stance
The silhouette of this 1970 model is defined by its aggressive fastback roofline and the massive, functional hood scoop required to clear the hemi-head V-8. Finished in factory Grabber Green, the car presents a visual character that is both period-correct and exceptionally bold. Exterior details include a functional front air spoiler, chrome bumpers, and the signature Boss 429 fender decals. The car sits purposefully on 15-inch Magnum 500 wheels wrapped in Goodyear Polyglas GT tires, maintaining the exact stance and presence it had when it was delivered new to Thompson Ford in Cuyahoga Falls, Ohio.
Pristine White Vinyl and Deluxe Decor Group
Inside the cockpit, the environment is a masterclass in Ford’s 1970 luxury-performance hybrid design. The cabin features high-back bucket seats trimmed in rare White vinyl, providing a sharp contrast to the Grabber Green exterior. Interior appointments from the Decor and Convenience groups include a center console, an electric clock, and the Rim Blow-Deluxe steering wheel. A tachometer and trip odometer provide critical data for the driver, while the Hurst T-handle shifter stands as a tactile reminder of the car’s competition-bred DNA. The inclusion of an AM radio and deluxe seatbelts with a warning light completes this highly original, time-capsule interior.
The 429 CI NASCAR Heart and Drag Pack Grit
Mechanical propulsion is provided by the legendary 429 CI V-8 engine, a powerplant famous for its massive aluminum heads and high-flow ports. This engine was factory rated at 375 hp / 380 PS and 450 lb-ft / 610 Nm, though these figures were notoriously underrated to satisfy insurance requirements. Power is managed through a close-ratio 4-speed manual transmission and a Drag Pack-equipped rear end, ensuring visceral acceleration and high-speed stability. The chassis is further refined by a factory competition suspension, power steering, and power front disc brakes, all of which were essential to manage the weight and output of the massive power unit.
