Pontiac V8 engine
The Pontiac V8 engine is a family of overhead valve 90° V8 engines manufactured by the Pontiac Division of General Motors Corporation between 1955 and 1981. The engine featured a cast iron block and head and 2 valves per cylinder. Engine block and cylinder heads were cast at Saginaw Metal Casting Operations then assembled at Tonawanda Engine before delivery to Pontiac Assembly for installation.

Initially marketed as a , it went on to be manufactured in displacements between and in carburated, fuel injected, and turbocharged versions. In the 1960s the popular version, which had helped establish the Pontiac GTO as a premier muscle car, was cut in half to produce an unusual, high-torque inline four economy engine, the Trophy 4. 

Unusual for a major automaker, Pontiac did not have the customary "small-block" and "big-block" engine families common to other GM divisions, Ford, and Chrysler. Effectively, Pontiac's V8s were all small blocks, sharing the same connecting rod length 6.625 in (168.3 mm) (except for the later short deck 301 and 265 produced in the late '70s and early '80s before Pontiac adopted universal GM engines).

The V8 was finally phased out in 1981, replaced by a GM "corporate engines" such as the Chevrolet 305 cu in small block V8.
