ZZ6 Crate Engine – Chevrolet Performance ZZ6 Turn-Key Small Block Crate Engine

ZZ6 Turn-Key Crate Engine

The ZZ6 is the ultimate 350-based turn-key crate engine from Chevrolet Performance!

The ZZ6 is one of the most powerful 350-based crate engines in the more than 25-year history of Chevrolet Performance’s ZZ crate engine lineup. It uses aluminum Fast Burn cylinder heads and LS-style beehive valve springs for higher-RPM performance. Rated at 405 horsepower and 406 lb.-ft. of torque it’s more powerful than any GEN I Small-Block engine ever offered in a production Chevrolet muscle car or Corvette!

What’s Included

Built with a cast-iron block with four-bolt mains, the ZZ6 includes a forged steel crankshaft, aggressive hydraulic roller camshaft, and durable, high-silicon pistons. Motorsports-inspired valve covers and Chevy “Bowtie” insignias on the ends of the cylinder heads let everyone know you’ve got the latest Chevrolet Performance hardware under the hood.

This turn-key engine package includes the distributor, and balancer installed. The carburetor, starter, air conditioning pump, alternator, single belt Front-End Accessory Drive Kit, and more are also included. The ZZ6 engine does not include a fuel pump. Chevrolet Performance offers the ZZ6 350 base engine (P/N 19355668) at a lower price, allowing you to finish the engine yourself.
