1966 Pontiac GTO 389CI V-8 Tri-Power making 360hp

For 1966, the GTO could be had with two different 389CI V-8s. The standard single four-barrel carb engine made 335hp, and the infamous Tri-Power making 360hp. The next year the cubic inches were increased to 400 and the tri-Power disappeared, but the base engine remained at 335hp. The GTO for sale here is a 66' vintage, but with the heart of a 400CI from a later 68' model year.
