Anniversary Edition 427 Crate Engine

Evoking the Legendary ZL1!

An instant legend was created in 1969 when a few enterprising dealers used Chevrolet’s COPO special order system to get the factory to build a handful of Camaros with the all-aluminum ZL1 427 racing engine. Chevrolet Performance commemorates the historic engine with the Anniversary Edition 427. It’s the perfect choice for a resto-mod ZL1 tribute!

Our special aluminum block casting is based on the original, and updated with screw-in galley plugs and additional features. An all-forged rotating assembly is used for strength and durability, while a hydraulic camshaft is used in place of the original ZL1’s flat tappet cam for greater drivability. We also use aluminum oval-port cylinder heads with large 2.19/1.88-inch valves for great airflow characteristics.

Only 427 serialized examples of this unique engine were built. Each numbered crate engine includes a special owner’s kit with an authenticity certificate, special 427 emblems and more.
