Chevrolet Performances big-torque ZZ383 is more powerful than ever. Weve added revised cylinder heads that incorporate a new, high-rpm valvetrain to help the ZZ383 produce 450 horsepower and 450 lb.-ft. of torque – 25 hp and 25 lb.-ft. more than the previous version! The new, lightweight aluminum cylinder head casting is based on the proven Fast Burn design, with large intake runners and 2.00/1.55- inch valves. New beehive-style valve springs enable greater high-rpm performance and durability. They allow the ZZ383 to rev higher, building more power to complement its low-rpm torque. The ZZ383 built with a brand-new block with four-bolt mains. It also features a forged steel crankshaft, an aggressive hydraulic roller camshaft and durable, high-silicon pistons. Unique valve covers distinguish the engine from previous versions and it now includes a high-flow, aluminum intake manifold! Instock & ready to ship now! #vpwracing #zz383 #chevroletperformance
