SP350/357 Deluxe Crate Engine
A Powerful, Durable and Affordable Small-Block 350!
As the latest in the Chevrolet Performance Street Performance crate motor lineup, the SP350/357 is designed as an affordable performer to fill the gap between the 350 HO and the SP350/385.
Starting with the 350 HO, GM engineers upgraded to a hydraulic roller cam and added the latest intake manifold design. Together, they bump the power to 357 hp and 407 lb.-ft. of torque.
The Chevrolet Performance SP350/357 Deluxe package includes the intake manifold, distributor, damper and flexplate.
