Pontiac V8
The GTO's 389 and Tri-Power, Ram Air II to IV, the 455 and the '77 Trans Am's W72.
Pontiac’s own V8 in the 389, 400 and 455: the GTO from its first Tri-Power to the Judge’s Ram Air III, the Ram Air IV with its round-port heads, the 455, and the 1977 Trans Am’s W72 at the end of the line. Every build comes with its gearbox, a Muncie or a Turbo Hydra-Matic, and there’s a Tri-Power crate engine with headers at the speed shops.
