4. Ford Mustang Boss 429 (1969-1970)
The Ford Mustang Boss 429 was no ordinary pony car.
Stuffed under the hood was a colossal semi-hemi 429 V8, specially developed for NASCAR homologation.
Ford shoehorned this engineering marvel into the Mustang, resulting in a true beast that offered jaw-dropping acceleration and a menacing presence.
Its unique engine and low production numbers have turned the Boss 429 into a rare and revered classic, standing apart from every other Mustang.
