Product Details


A NEW STANDARD FOR AFFORDABLE SMALL-BLOCK PERFORMANCE!
If it’s affordable performance you’re looking for to power your project vehicle, Chevrolet Performance’s SP350/357 delivers! With 357 horsepower and a deep reserve of low-rpm torque, it quickly reminds you why Chevrolet’s original 350 Small-Block has been the industry benchmark for decades.

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. A roller camshaft optimizes drivability and airflow capability. It all adds up to a 24-horsepower gain over our 350 HO crate engine – and a great, affordable alternative to rebuilding.

Does not include oil filter or adapter see below for part numbers. 

For more complete crate engines, see the SP350/357 Deluxe P/N 12677170 and the SP350/357 Turn-Key P/N 12677177.
