Overview

Chevrolet Performance Connect and Cruise ZZ6 Engine and Transmission Packages

Chevrolet Performance engineers did all the hard work, designing and calibrating carefully matched Connect and Cruise powertrain systems for optimal compatibility and performance—while also identifying the complementing engine and transmission controllers, torque converters and supporting installation kits. The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation—and, more importantly—operation without the need for third-party tuning.

Connect and Cruise ZZ6 Engine and Transmission packages are offered in three options: with Base engine, Turnkey engine, and EFI engine. ZZ6 engine details:

Rated at 405 hp and 406 lbs.-ft. of torque, the ZZ6 delivers more power than any 350 small block ever installed in a production vehicle. The cylinder head casting is based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves. Beehive-style valve springs deliver greater high-rpm performance and durability. The ZZ6 also uses an aggressive hydraulic roller camshaft.
