ZZ6 Turn-Key Chevrolet Performance Crate Engine

A ZZ6 That Is Ready To Run! 

The ZZ6 delivers more power than any 350 Small-Block 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 also included.

The Ultimate ‘ZZ’ 350-Based Crate Engine from Chevrolet Performance!

ZZ6 Base Crate Engine Located Here.

The all-new Chevrolet Performance ZZ6 crate engine is one of the most powerful 350 based crate motors in the more than 25-year history of the ‘ZZ’ crate engine lineup. It uses aluminum Fast Burn cylinder heads equipped with LS-style beehive valve springs for greater high-rpm performance. It’s rated at 405 hp and 406 lb.-ft. of torque - more than any Small Block engine ever offered in a production Chevy muscle car or Corvette!

The ZZ6 350 is built with a cast-iron block with four-bolt mains, along with a forged steel crankshaft, an aggressive hydraulic roller camshaft and durable, high-silicon pistons. All-new, motorsports-inspired valve covers distinguish this new crate motor at a glance, too – along with Chevy “Bowtie” insignias in the ends of the cylinder heads that let everyone know you’ve got the latest GM Performance hardware under the hood.

This Turn Key engine package includes the 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 also offers the ZZ6 350 base engine (P/N 19351532) at a lower price, allowing you to finish the engine yourself.
