Chevrolet Performance ZZ6 EFI Turnkey Crate Engines

Chevrolet Performance ZZ6 EFI Turnkey crate engines build 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. The 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 advantage 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. These Turnkey crate engine kits include the distributor and damper installed. The throttle body, air conditioning pump, alternator, single-belt front-end accessory drive kit, and more are also included.
