Chevrolet Performance 502 C.I. Deluxe Big-Block Crate Engine 508 HP

The Chevrolet Performance ZZ502 502 C.I. deluxe crate engine (19433162) is a proven big-block package that delivers 508 horsepower and the kind of torque that makes a heavy car or truck feel effortless. Its aluminum oval-port cylinder heads and hydraulic roller camshaft produce more than 500 lb.-ft. of torque from roughly 2,500 rpm to 5,000 rpm for strong low- and mid-range power. This engine is built around a cast-iron 4-bolt main block with a forged rotating assembly to handle aggressive street driving and weekend strip use. This deluxe package comes ready to run with major components already included, such as an HEI distributor, dual-plane intake manifold, Holley 870-cfm carburetor, starter, spark plug wires, water pump, and flexplate.
