Under the guidance of Semon Bunkie Knutson, John DeLorean, and a host of creative and invative 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 287ci, but it was an auspicious beginning to an illustrious line of engines. The potent power plant grew and evolved over the coming decades; it 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 want to rebuild these engines and give them a new lease on life. Long-time Pontiac expert and magazine writer Rocky Rotella guides the reader through the entire rebuild process. Drawing on his vast experience, Rotella uses detailed captions and explanatory photos to show each crucial step of the disassembly, inspection, machine work, parts selection, assembly, and break-in process. This book instructs the reader how to skillfully pull the engine and prevent damage to the car. It documents how to carefully inspect the components for problems and fix these issues that could spell doom for a newly rebuilt engine. Finding a reputable and professional machine shop that specializes in Pontiac engines is discussed, as well as aftermarket parts and OEM parts interchange for high performance so you can select the best parts for a particular engine. All essential machine shop procedures are covered in detail. Inspection and pre-assembly are thoroughly explained. Most important, as with all Workbench series titles, the methodical and practical approach provides the insight and vital information required for the task. This, the first-ever book dedicated to rebuilding the Pontiac V-8 engine, is a valuable addition to any Pontiac enthusiast's library.
