Chevrolet Performance SP350/357 Base Chevrolet Crate Engines

If it’s affordable performance you’re looking for to power your project vehicle, Chevrolet Performance’s SP350/357 Base Chevrolet crate engine delivers! With 357 hp 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 4-bolt mains, along with economical Vortec iron cylinder heads. A roller camshaft optimizes driveability and airflow capability. It all adds up to a 24 hp gain over CPP’s 350 HO crate engine—and a great, affordable alternative to rebuilding. This base crate engine package includes an assembled long block, including the oil pan. You finish it off your way, with the ignition system, induction system and additional accessories.
