More power from our classic Small-Block stroker

Chevrolet Performance’s big-torque SP383 Deluxe is more powerful than ever. We’ve added revised cylinder heads that incorporate a new, high-rpm valvetrain to help the SP383 Deluxe produce 435 horsepower and 445 lb-ft of torque. 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 SP383 Deluxe to rev higher, building more power to complement its low-rpm torque. The SP383 Deluxe is 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 small-block stroker running in your vehicle faster.
