- Chevrolet Performance ZZ6 Turn-Key 350ci/405HP Crate Engine
The Next Chapter in the ZZ Small-Block Legacy with Turn-Key Ease!
The all-new Chevrolet Performance ZZ6 crate engine is one of the most powerful 350 cubic inch based crate motors in the 25+ year history of the 'ZZ' crate engine lineup. It uses aluminum Fast Burn cylinder heads equipped 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. It's rated at 405 horsepower and 406 lb.-ft. of torque.
