MARK IV: THE BIG-BLOCK THAT ROARED!

A guide to the engine that made Chevrolet The Number One Team.
Between 1965 and 1976, Chevrolet’s iconic big-block distinguished itself in all forms of racing, and on the street in Corvettes, Camaros, Chevelles, Novas and full-size Chevys. Big-blocks started out with cast-iron blocks and heads, progressed to cast-iron block with aluminum heads (L-88) and peaked with aluminum block and heads (ZL-1).
