An Affordable Small-Block Performer!

With 357 horsepower and more than 400 lb.-ft. of torque, the Chevrolet Performance 350/357 Turn-Key offers a great combination of performance and value.

Modern valvetrain technology is the key to its high-revving capability, pushing power to 5,500 rpm, while economical iron cylinder heads deliver excellent airflow and help make this potent crate engine more affordable. They’re matched with a friction-reducing roller camshaft that helps optimize performance across the rpm band.

The rest of 350/357 Turn-Key is built with strong, all-new components, including a brand-new four-bolt block, a durable nodular iron crankshaft and more. As one of our Turn-Key crate engines, it also includes an aluminum intake manifold, Holley four-barrel carburetor and HEI distributor and balancer installed, while a starter, water pump and front-end accessory drive kit—including an air conditioning compressor, alternator and more—are also included (installation required).

Chevrolet Performance also offers the SP350/357 Base crate engine, P/N 12677167 as well as the SP350/357 Deluxe P/N 12677170.
