Built for just two short years, the Ford Boss 429 V8 still casts a long shadow in the world of Ford performance. Nicknamed the “Twisted Hemi”, this engine was originally designed for NASCAR dominance, featuring a unique hemispherical combustion chamber and an advanced valvetrain layout.
With aluminum cylinder heads and a Cooper ring sealing system (instead of traditional head gaskets), the Boss 429 was a bold leap in engineering. It scored its first NASCAR win in 1969 with Cale Yarborough behind the wheel in Atlanta—marking the beginning of a legendary legacy.
