1967 Pontiac GTO
The GTO was the undisputed king of the muscle car movement. But in 1967, this model received an important mechanical update, keeping it on the top. Design-wise, they changed little, but under the hood, it was significant.
The venerable 389 V8 with the Tri Power option was gone. Pontiac replaced it by the new 400 V8 which came with the famous Ram Air intake system. This change allowed the GTO to deliver even better performance numbers. Also, it opened the doors to more powerful and faster cars from Pontiac.
