Even though the 502 is a great value, don't think for a minute that Chevrolet Performance Parts skimped on parts or validation of those parts to the highest standard in the industry. 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 roller camshaft controls the airflow through our legendary rectangular-port cast iron cylinder heads -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, so that when outfitted with the 502 HO, your performance GM car will make tremendous power from just pump gas.
Chevrolet Performance Parts has completed this amazing crate engine with an aluminum dual-plane intake manifold, cast iron water pump, 6-quart oil pan (with windage tray), damper, and a 14" flexplate. Pick the carburetor, starter, ignition system, and you are on your way to big-block bliss!
Chevrolet Performance Parts started with the 454 that everyone loves and pumped it up to a 502 cubic inch powerhouse that delivers 550 ft/lbs TQ (3500 RPM) with 450 HP (5250 RPM).
