Chevy to Unveil New 405 Horsepower Small Block Crate Engine at SEMA

If you’ve got a project car waiting for its powerplant, you might want to consider Chevrolet Performance’s newest ZZ6 crate engine that will be officially unveiled at the SEMA show next month.

The new engine will produce 405 horsepower and 405 lb-ft of torque, more than enough to put some pep in that old car you’re restoring.

In fact, the ZZ6 produces more power than any factory produced 350 engine ever installed in a Chevrolet production vehicle and is one of the most powerful 350 Small Block-based crate engines during the 27-history of the ZZ lineup.

“The new ZZ6 is the ultimate ZZ 350-based crate engine from Chevrolet Performance,” said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. “After more than six decades, our powertrain engineers continue to refine and update the classic Small Block architecture, adapting new technologies to advance the legacy of the industry’s most adaptable V-8 engine and giving customers new choices from the company that pioneered the concept of high-performance crate engines.”

The engine uses modern technologies, including updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family to enhance high-rpm capability.

You’ll be able to buy two versions of the engine – the Base kit that will include single-plane aluminum intake, distributor, water pump, damper and flexplate but no carburetor and other accessories, or the Turn Key kit that will add the carburetor, air cleaner matching the unique valve covers, starter, distributor, alternator, air conditioning compressor, and front-end accessory drive system.
