The Mustang Boss 429 (also known as the “Boss 9” by enthusiasts) is arguably one of the rarest and most valued muscle cars to date. In total there were 859 original Mustang Boss 429s made. The origin of the Mustang Boss 429 comes about as a result of NASCAR. Ford was seeking to develop a Hemi engine that could compete with the famed 426 Hemi from Chrysler in NASCAR’s Sprint Cup Championship Series (then known as “Grand National Division”). NASCAR’s homologation rules required that at least 500 cars be fitted with this motor and sold to the general public. After much consideration, it was decided by Ford that the Mustang would be the car that would house this new engine.
The Boss 429 engine was derived from the Ford 385 engine. It used four bolt mains, a forged steel crank and forged steel connecting rods. The engine featured aluminum cylinder heads, which had a modified Hemi type combustion chamber which Ford called “crescent”. These heads used the “dry-deck” method, meaning no head gaskets were used. Each cylinder, oil passage and water passage had an individual “O” ring style seal to seal it tight. The Boss 429 engine used a single Holley four barrel carburetor rated at 735 CFM mounted on an aluminum intake manifold that flowed well for its time. 1969 cars featured a hydraulic lifter camshaft while 1970 models got a mechanical lifter camshaft along with an improved dual exhaust system though rated power output stayed the same.
