ZZ6 EFI Deluxe Crate Engine

19368149 Chevrolet Engine

The ZZ6 EFI crate engine combines the drivability advantages of electronically controlled fuel injection with the versatility of the 350 Small-Block, pumping out 420 hp @ 5800 rpm and 408 lb-ft torque @ 4500 rpm. A traditional air filter option blends together horsepower and appearance without the need for third-party tuning, and its proven Fast Burn design and 2.00/1.55-inch valve springs support great performance and durability, resulting in a high rev while making the most out of every cubic inch.

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 Deluxe package includes the distributor, damper, and flexplate.
