Chevrolet Performance 19368150 - ZZ6 EFI Turn Key Crate Engine - 420HP


The ZZ6 EFI Turn-Key crate engine offers modern performance balanced with traditional style that looks period perfect in your vintage Chevy!

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 cleaner to be installed on the engine.

The ZZ6 also features cylinder heads based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves, along with beehive-style valve springs enable greater high-rpm performance and durability. It also uses an aggressive hydraulic roller camshaft that supports the engine’s high-rpm airflow capability while maintaining excellent low-speed drivability.

A simple plug-and-play control system rounds out the package to get the engine running in your project without the need for third-party tuning.

The Turn-Key crate engine kit includes the distributor and damper installed, with the throttle body, starter, fuel pump, air conditioning pump, alternator, single-belt Front-End Accessory Drive Kit and more also included. Chevrolet Performance also offers the ZZ6 EFI Deluxe kit, which includes the installed distributor and damper.
