THE ENGINE THAT BRINGS COMPETITIVE PERFORMACE FOR ANY BUDGET

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 strong components and modern technology to make it a better alternative to rebuilding.

The SP350/357 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 high-rpm capability.
