MORE POWER FROM OUR CLASSIC SMALL-BLOCK STROKER

Chevrolet Performance’s big-torque ZZ383 is more powerful than ever. We’ve 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! Use the Holley 770-cfm four-barrel carburetor P/N 19170093 to make the most of the engine’s capability and achieve the listed horsepower and torque ratings. Your Chevrolet Performance dealer has everything you need to finish off the engine and get this stroker small-block running in your vehicle faster.
