ZZ6 Turn-Key Crate Engine With Front End Accessories, Carb, Starter, Fuel Pump

Chevrolet Performance’s new ZZ6 delivers more power than any 350 Small-Block ever installed in a production vehicle. Rated at 405 hp and 406 lb.-ft. of torque, it derives its range-topping performance from unique, 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. Their egg-shaped profiles have less reciprocating mass in motion, require less spring pressure for greater valve control and handle valvetrain stresses more efficiently. They allow the ZZ6 to rev higher to make the most of every cubic inch of air drawn through it. The ZZ6 also uses an aggressive hydraulic roller camshaft that supports the engine’s high-rpm airflow capabilitywhile maintaining excellent low-speed drivability. This Base crate engine kit includes the intake manifold, distributor,water pump, damper and flexplate – and the distinctive, racing-inspired valve covers that distinguish this crate engine as the latest in the ZZ legacy!

This Turn-Key engine package includes the ZZ6 base engine with distributor, and balancer installed. The carburetor, starter, fuel pump, air conditioning pump, alternator, single belt front-end accessory drive kit and more are also included. Chevrolet Performance offers the ZZ6 350 base engine (P/N 19351532) at a lower price, allowing you to finish the engine yourself.
