Description Technical Specs Extended Information
 
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.

GM Performance Parts has recreated that classic Big-Block 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 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, the ZZ427/480 is
the heritage-inspired crate engine that delivers the performance that built
the Big-Block’s legendary reputation.

Note: This engine WILL NOT work in Corvettes without hood modification.
