Ford Mustang Cobra Jet 428
The legendary 428 Cobra Jet debuted in 1968, and Ford immediately put it in the Mustang. The Mustang 428 CJ was a mid-year introduction designed for drag racing, which is why very few left the factory (via Hemmings).
But this was a true beast of a car with a 390 hp engine, light body, and four-speed close ratio manual transmission. With a 0 to 60 mph time of just 5.4 seconds, this was the fastest stock car of the era. It remains a highly valuable collector’s item today.
