Description
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 mimics the appearance of a classic carbureted setup. A throttle body mounted in place of a carburetor allows a traditional air cleaner to be installed seamlessly.
The ZZ6 features aluminum Fast Burn cylinder heads with large intake runners, 2.00/1.55-inch valves, and beehive-style valve springs for high-RPM durability. Paired with an aggressive hydraulic roller camshaft, it supports high-RPM airflow 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 requiring third-party custom tuning.
The Turn-Key crate engine package includes the distributor and damper installed, along with the throttle body, starter, A/C compressor, alternator, single-belt front-end accessory drive (FEAD) system, and wiring harness.
