Chevrolet Performance ZZ427/480 Crate Engine
Chevrolet Performance's modern interpretation of the legendary
L88 427 Between 1967 and 1969, the alphanumeric designation that struck fear from Main Street to the drag strip was L88. It was the ultimate expression of Chevy's Big-Block power, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single four-barrel carburetor.
Chevrolet Performance has recreated that classic Big-Block crate engine combination in the ZZ427/480, rated at 480 horsepower. Like the original, it features an iron block, forged steel crankshaft and high-flow aluminum cylinder heads.
We've upgraded the camshaft from the original's mechanical flat-tappet
design to a more contemporary hydraulic roller, giving this 21st-century
L88 modern drivability characteristics and a greater rev range. A lower
10.1:1 compression ratio makes it pump gas-friendly, too. The original L88,
born in the time of leaded gasoline, had 12.5:1 compression.
The ZZ427/480 crate engine comes complete with high-flow oval-port heads, a highlift
camshaft (0.510-inch intake/0.540-inch exhaust), an aluminum intake
manifold, 870-cfm Holley carburetor, an HEI distributor, aluminum water
pump, balancer, spark plug wires and a 14-inch flexplate.
Whether you're building a '69 COPO Camaro resto-mod tribute, a
modified mid-year Corvette or a street-tire class winner, Chevrolet Performance's ZZ427/480 is
the heritage-inspired crate engine that delivers the performance that built
the Big-Block's legendary reputation.
