ZZ502/502 Base is a great foundation for the builder who wants the super strong bottom end and high-flow aluminum oval-port cylinder heads. A set of high-flow aluminum oval-port cylinder heads and a hydraulic roller camshaft designed to support low-rpm torque production enable it to hit the 500 lb.-ft. mark by approximately 2,500 rpm and hold it above the mark until around 5,000 rpm. Features a latest-generation block casting with four-bolt main caps and an all forged rotating assembly for exceptional strength and durability. It is rated at 508 horsepower and 580 lb.-ft. of torque when it is finished with Chevy’s aluminum intake manifold P/N 12363406 and Holley 870-cfm carburetor P/N 19170094.
Chevrolet starts with a Gen VI 4-bolt main block with a one-piece rear main seal and priority oiling for the main bearings. To that, they add: an externally balanced, forged crank that’s shot-peened and magnafluxed; forged steel “dimple” connecting rods; forged aluminum pistons; a single-roller heavy-duty timing chain set; and a hydraulic roller camshaft. The cam has 0.527 in. of intake lift and 0.544 exhaust lift, with 110 degrees of lobe separation. Duration at 0.050 in. of lift is 224 degrees for the intakes, and 234 for the exhausts.
