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.

Based on the value-driven 350 HO crate engine, our engineers swapped the flat-tappet camshaft for a hydraulic roller and added the latest Small-Block intake manifold design. Together, they help build more power across the rpm band – 357 horsepower and 407 lb.-ft. of tire-turning torque.

Chevrolet Performance also offers the SP350/357 Base crate engine, P/N 12677167. TECH SPECS
