The Boss 429 engine was derived from the Ford 385 engine. The Mustang's body however was not wide enough to encompass the massive Boss 429 engine and as a result, Ford hired Kar Kraft out of Dearborn, MI to modify existing 428 Cobra Jet Mach 1 Mustangs to properly fit the new Boss 429 engine. Kar Kraft was contracted by Ford to create the Boss 429, because Ford was stretching itself thin across a number of projects. Kar Kraft at the time was in the process of creating the Trans-Am Boss 302. Production on the Boss 429 began in 1968 in Brighton, Michigan at Kar-Kraft's factory; the cars were transported to this plant directly from the auto maker's plant and the work began. Kar Kraft made extensive modifications to the Mustang, including widening the shock towers and extended out the inner fenders to allow this massive engine to fit. The mounts for the front suspension were chopped and displaced to create room for the block and exhaust manifolds.[1] Next the battery was repositioned to the trunk and a stiff sway bar was added to rear end. In addition, a hole was cut in the hood and a manual controlled hood scoop was added to these cars. These cars were rated conservatively at 375 hp (280 kW) and 450 lb?ft (610 N?m) of torque. Actual output was well over 500 horsepower (370 kW). The manufacturers and dealers only listed 375 hp (280 kW) because of legal issues and rising insurance costs.[2]
In 1969 there were 859 Boss 429s
In 1970 there were 499 Boss 429s
