History

In the late 1960s, Ford was looking to compete in NASCAR racing against the likes of Chrysler’s Hemi engine. To be eligible for NASCAR, manufacturers were required to produce a minimum number of cars for public consumption. Ford’s solution was to create a limited edition Mustang, the Boss 429.

The Boss 429 was powered by a massive 429 cubic inch V-8 engine, which was specially designed for NASCAR racing. The engine was so large that it had to be installed at Kar Kraft, a subsidiary of Ford, which modified the Mustang’s shock towers and suspension to accommodate the massive engine.

Specifications

The 1970 Boss 429 was equipped with a 429/375 HP 820-T V-8 engine, which was capable of producing 375 horsepower and 450 lb-ft of torque. It had a 4-speed transmission and a 3.91 Traction-Lok rear end. The car also had a competition suspension, power brakes with front discs, and a front spoiler.

Inside, the Boss 429 featured Clarion knit Corinthian vinyl bucket seats, a center console, and an AM radio. The Hurst T-handle shifter added to the car’s racing pedigree. The exterior of the car featured Goodyear Polyglas tires and Magnum 500 wheels. The Grabber Blue with White interior color combination was highly desirable and added to the car’s overall aesthetic appeal.
