Chevrolet Performance 502HO 502ci/450HP Engine
The Chevrolet 502 HO Engine is what all big-block crate engines should be and that is maximum power with a maximum return on your money invested! The 502 HO bottom end consists of a cast iron four-bolt block, forged steel crankshaft, forged steel connecting rods that have been shot-peened for durability, and forged pistons. A high-lift hydraulic roller camshaft controls the airflow through our legendary rectangular-port cast iron cylinder heads for more than enough air to fill those hungry 502 cubes! One other key engineering feature is that the final compression ratio comes in at 8.75:1, which will make tremendous power from just pump gas!
