Chevrolet Performance ZZ6 EFI Deluxe Crate Engine

Chevrolet Performance engineers adapted a unique, electronically controlled port fuel-injection system to the ZZ6 350, using an aluminum intake manifold that has the appearance of a carbureted intake. A fuel-injection throttle body mounted in place of the carburetor allows a traditional air filter to be installed on the engine. The ZZ6 also features cylinder heads based on the proven Fast Burn design with beehive style valve springs.

The Deluxe package includes the distributor, damper, and flexplate.
