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.

a brand-new four-bolt block, a durable nodular iron crankshaft and more. The
Turn-Key Engine comes with the intake manifold and distributor installed. It
also includes the carburetor, front-end accessory kit, chrome air cleaner, starter,
and spark plug wires (some installation required).
