Chevrolet Performance has recreated the classic L88 Big-Block combination in the ZZ427/480 crate engine. Rated at 480 horsepower, it features an iron block, forged steel crankshaft and high-flow aluminum cylinder heads. An upgraded hydraulic roller camshaft improves drivability and PRM range while lower 10.1:1 compression means you can enjoy the power on pump gas too. The ZZ427 comes complete with high-flow oval port heads, a high-lift camshaft, an aluminum intake manifold, 770cfm Holley carburetor, an HEI distributor, aluminum water pump, balancer, spark plug wires and a 14in flexplate.
