BBC ZZ572 Crate Engine with T56 6 Speed Chevrolet Performance CPSZZ572T56

New Connect and Cruise Package

Chevrolet Performance is breaking new ground with the launch of the new Connect-and-Cruise crate powertrain systems. They're factory-engineered engine-and-transmission combinations that include all the electronic control modules, wiring harnesses and other key components you need with the simplicity of one part number. Our engineers matched the engines and transmissions for optimal performance and durability, so you can wring out all the horsepower from them with total confidence. The specially calibrated controllers are designed for retrofit installation in older vehicles, for easier and quicker installation and operation, without the need for third-party tuning. Each one comes with an installation kit, including flex plates, covers and other important components to keep typical mid-project parts chasing to a minimum.
