Pontiac Straight-8 Engine

Pontiac Straight-8 Engine

The straight-8 was an eight-cylinder, in-line automobile engine that was used in production Pontiacs from 1933 to 1954. Introduced in the fall of 1932 for the 1933 models, it was Pontiac's most powerful engine at the time and was the least expensive eight-cylinder engine built by an American automotive manufacturer. During its 21 year run, displacement of the "eight" increased twice as platforms grew. It was superseded by Pontiac's new V8, the 287, in 1955.
