Mustangs' were simply too small to accept the massive Boss 429 engine so Ford hired Kar Kraft of Brighton, Michigan to modify existing 428 Cobra Jet and Super Cobra Jet Mach 1 Mustangs. All these cars had the Hurst Competition Shifter 4-Speed Manual Transmissions and the Boss was rated very conservatively at 375 HP while actual output was believed to be well over 500 horsepower. The Boss 429 engine used a single Holley four-barrel carburetor rated at 735 CFM mounted on an aluminum intake manifold. The Boss 429 engine featured aluminum cylinder heads, which had a modified Hemi type combustion chamber which Ford called "crescent". NASCAR required that at least 500 cars be fitted with the competition motor and sold to the general public. Ford was seeking to develop a Hemi engine that could take on the Mopar Hemi boys - the 426 Hemi Charger Daytona and the Plymouth Superbirds - the monsters for Ford to slay to achieve their desire to rule the track. The origin of the Boss 429 was as a result of Ford’s desire to compete in NASCAR. In total there were 859 original ’69 Boss 429s then only 499 Boss 429’s for the 1970 model year. The Boss 429, sometimes referred to as the "Boss 9" by blue oval enthusiasts, is arguably one of the rarest and most valued muscle cars from the era. ![]() ![]() LMC is very proud to offer for sale this 1970 Ford Mustang Boss 429 “Orange Blossom III” ![]()
