Ford Mustang Cobra Jet
Ford revealed the legendary 428 Cobra Jet engine in 1968 and immediately put it in the Mustang. The Mustang 428 CJ was a mid-year introduction they mostly intended for drag racing. And that is why they sold it in modest numbers.
Ford rated the new 428 Cobra Jet at 335 HP, but everybody knew the new big block produced far more than that. The real output of race-prepared white Fastbacks was closer to the 500 HP mark. Even with less power than some competitors, the Mustang managed to win races since it was smaller, lighter and better balanced than those Mopars.
