Under the guidance of Semon "Bunkie" Knutson, John DeLorean, and a host of creative and innovative people, Pontiac established its own identity and distinct V-8 engine platform under the GM banner. In 1955, Pontiac's V-8 started out at a meager 287 cubic inches, but it was an auspicious beginning to an illustrious line of engines. The potent powerplant grew and evolved over the coming decades, which included the 389 Tri-Power, 421, Ram Air IV 400, 428, and the Super Duty 455. These V-8s powered a number of legendary cars the GTO, Firebird, Trans-Am, and many others. This Workbench series book will guide proud owners who will rebuild these engines and give them a new lease on life
