Crate Engines

SP350CI - 357HP Turn Key Chevrolet Performance’s line of Street Performance engines offers great power at a great value – and the latest is the SP350/357. It leverages the strength of a strong rotating assembly secured in a brand-new block with four- bolt mains, and matches it with modern valvetrain technology to support great high-rpm capability.

ZZ6 EFI Deluxe 420HP The ZZ6 EFI crate engine combines the drivability advantages of electronically controlled fuel injection with the versatility of the 350 Small-Block, pumping out 420 hp @ 5800 rpm and 408 lb-ft torque @ 4500 rpm. A traditional air filter option blends together horsepower and appearance without the need for third-party tuning, and its proven Fast Burn design and 2.00/1.55-inch valve springs support great performance and durability, resulting in a high rev while making the most out of every cubic inch.
