14. 1968 Ford Mustang Cobra Jet
Ford introduced the legendary 428 Cobra Jet in 1968 and immediately put it in the Mustang. The Mustang 428 CJ was a mid-year introduction mostly intended for drag racing. That is why it was sold in modest numbers. But the real drag racing special was 50 Wimbledon white Fastbacks. They came with the 428 CJ engine and were lightweight.
They also had a close-ratio four-speed transmission and heavy-duty suspension to satisfy the NHRA rules. Ford rated the new 428 Cobra Jet at 335 HP, but everybody knew the 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 won races since it was smaller, lighter and better balanced than most Mopars.
