POWER, DURABILITY AND AFFORDABILITY IN THE CLASSIC SMALL-BLOCK 350!
As the latest in Chevrolet Performance's Street Performance crate engine lineup, the SP350/357 is designed as an affordable performer to match just about any budget. Better still, it uses stronger components and modern technology to make it a better alternative to rebuilding.
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.
The SP350/357 leverages the strength of a strong rotating assembly secured in a brand-new block with four-bolt mains, along with economical Vortec iron cylinder heads. It's a durable assembly designed to offer years of highperformance excitement at an excellent value.
Our SP350/357 Deluxe package includes the intake manifold, distributor, damper and flexplate. Chevrolet Performance also offers the SP350/357 Base crate engine, P/N 12677167.
