4. Ford Mustang 390 GT
The Mustang got its first redesign in 1967 when Ford introduced a slightly bigger and more luxurious model. The design was even better and more elegant and the options list was longer than ever. The performance lovers finally got a big block option in the form of the 390 FE V8 engine which produced 325 HP.
This was a fast and powerful car, but it was more of a Grand Tourer than a muscle car. The reason was the engine which Ford took from the Thunderbird. In the end, the 390 GT was more suited for effortless cruising than for drag racing.
