An Affordable Small-Block Performer Ready to Run!

Chevrolet Performance’s line of Small-Block crate engines offers great power at a great value. The SP350/357 Turn-Key leverages the strength of a strong rotating assembly and matches it with modern valvetrain technology to support great high-rpm capability.

Economical iron cylinder heads deliver excellent airflow, while the latest intake manifold technology and a new hydraulic roller camshaft optimize airflow to push 357 horsepower and more than 400 lb.-ft. of torque! Better still, the engine is built with a durable nodular iron crankshaft and powdered metal connecting rods set in a brand-new block with four-bolt mains. That’s a feature you won’t find on most rebuildable cores.
