ZZ427/480 Crate Engine

The L88 427 was the ultimate expression of Chevy‘s production Big Block power, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single four-barrel carburetor. GM engineers have recreated that classic, raspy rat engine in the Chevrolet Performance ZZ427/480 crate engine, but with updated components that enhance drivability and performance.

This Chevy engine is a modern take on the classic L88. The engine assembly features the latest-generation block casting with four-bolt main caps, an all-forged rotating assembly for exceptional strength and durability and a hydraulic roller camshaft instead of the original L88’s flat-tappet cam, for greater drivability and a broader performance range. It also features aluminum oval-port cylinder heads with 2.19/1.88-inch valves and a pump-gas-friendly 10.0:1 compression ratio.

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 motor that delivers the performance that gave the Chevy Big Block its legendary reputation.

Important Notes:

  • Requires addition of starter and fuel pump (not included).
  • Recommended Transmission: SuperMatic 4L85-E Four-Speed Automatic P/N 19300175
  • Due to crate fitment, the carburetor is shipped in a separate box and needs to be installed by an engine installer.
  • Clutch linkage bosses are drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads for clearance.
  • Comes with an internally balanced 14″ automatic transmission flexplate. Requires flywheel designed for internally balanced engines.
  • Designed for pre-1976 street vehicles or any off road vehicle.
  • Not intended for marine applications.

Note: Distributor with melonized steel gear MUST be used with long-blocks and partial engines with steel camshafts, or engine damage will occur.
