MOLDING KIT

Chevrolet Performance’s SP350/385 Turn-Key uses aluminum Fast Burn cylinder heads equipped with LS-style beehive valve springs for greater high-rpm performance that helps this power-dense engine offer 385 horsepower and 405 lb.-ft. of torque. The lightweight cylinder head casting features large, 210cc intake runners, with the beehive valve springs matched with steel retainers, machined steel spring seats and split key locks. The beehive-style valve springs allow the SP350/385 to rev higher to make the most of every cubic inch of air drawn through it. Like all of our Small-Block crate engines, this one is built with a brand-new block with four-bolt mains and it features a hydraulic roller camshaft. The turn-key engine package includes the distributor, carburetor, and balancer installed. The front-end accessory kit, chrome air cleaner, starter, and spark plug wires are also included (some installation required).
