Fuel-injected performance and convenience from the ZZ6!
The ZZ6 EFI Turn-Key builds on more than 65 years of Small-Block heritage and the legacy of the pioneering “ZZ” crate engine family to offer thoroughly modern performance balanced with traditional style.
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. The result is a great, traditional appearance and all the drivability advantages of EFI on the highway.
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. Our Turn-Key crate engine kit includes the distributor and damper installed. The throttle body, single-belt front-end accessory drive kit, and starter are also included (some installation required).
