The ZZ6 delivers more power than any 350 Small-Block Chevy ever installed in a GM production vehicle. Rated at 405 hp and 406 lb.-ft. of torque, it features lightweight aluminum cylinder heads that enable optimal airflow at high rpm. 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 features an aggressive hydraulic roller camshaft.

This Turn-Key engine package includes the intake, distributor and balancer installed. The carburetor, starter, fuel pump, air conditioning pump, alternator, serpentine belt front-end accessory drive kit and more are all included.

It’s all backed by the 4L65-E four-speed overdrive automatic, which enables great highway cruising performance and fuel economy, while retaining good off-the-line performance with the steep first gear ratio. It is tough as nails too, with the durability of hardened internal parts and five-pinion gearsets.
