The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet Division of General Motors between 1954 and 2003, using the same basic engine block. Referred to as a “small-block” for its comparative size relative to the physically much larger Chevrolet big-block engines, the family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) in displacement. Engineer Ed Cole is credited with leading the design for this engine.
