Chevrolet Performance ZZ427/480 HP Long Block Crate Engines
Chevrolet Performance has recreated the classic L88 Big Block combination in the ZZ427/480 long block crate engine. Rated at 480 hp, it features an iron block, forged steel crankshaft, and high-flow aluminum cylinder heads. An upgraded hydraulic roller camshaft improves drivability and rpm 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, aluminum intake manifold, 770 cfm Holley carburetor, an HEI distributor, aluminum water pump, balancer, spark plug wires, and a 14 in. flexplate. If you’re looking for a modern version of the classic L88, the Chevrolet Performance ZZ427/480 long block crate engine is the answer.
