Pontiac V8 engine
From 1955 to 1981 the Pontiac Division of General Motors manufactured its own, unique V8 engines. Displacement began at 287 in³ and grew as large as 455 in³ (7.5 L) by 1970. An engine of intermediate size (neither a true small-block nor big-block), the Pontiac V8 was a unique design, distinct from Buick, Chevrolet, or Oldsmobile engines. Pontiac's engines were used in its U.S.-market cars; Canadian Pontiacs generally used Chevrolet engines. From 1955 through 1959 Pontiac's V8 was also used in GMC pick-up trucks.
The 287-V8 engine was introduced for the 1955 model year as the "Strato Streak". Not long before the model year introduction, Pontiac management decided that the entire line would be V8-powered.
