They allow the SP350 to rev higher to make the most of every cubic inch of air drawn through it. The SP350 is built with a brand-new block with four-bolt mains, along with a forged-steel crankshaft, an aggressive hydraulic roller camshaft, and durable, high-silicon pistons. Unique valve covers distinguish this new crate engine at a glance, too-along with Chevy bow tie insignias in the ends of the cylinder heads that let everyone know you have the latest Chevrolet Performance hardware under the hood.
The Turn Key engine package includes the distributor, carburetor, and balancer installed. The starter, fuel pump, air conditioning pump, alternator, front-end accessory drive kit, and more are also included.
