Small Block 383 Stroker

Free Shipping!

Chevrolet Performance's big-torque SP383 is more powerful than ever. Chevrolet added their revised cylinder heads that incorporate a new, high-rpm valvetrain to help the SP383 produce 435 horsepower and 445 lb-ft of torque. The new, lightweight aluminum cylinder head casting is based on the proven Fast Burn design. They feature 62cc chamber, 210cc intake runners, 2.00'' hollow stem intake/1.55'' sodium-filled exhaust valves, Blue beehive valve springs, steel retainers, machined steel spring seats and split key locks, D-shaped exhaust ports, dual intake bolt pattern, standard perimeter and center-bolt valve cover bolt patterns, Angled Spark Plugs (5/8" Hex, 3/4" Reach, Tapered Plugs). The beehive-style valve springs enable greater high-rpm performance and durability. They allow the SP383 to rev higher, building more power to complement its low-rpm torque.

The SP383 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 809-19170093) or (p/n 510-0-83770) to make the most of the engine's capability and achieve the listed horsepower and torque ratings. JEGS has everything you need to finish off the engine and get this small-block stroker running in your vehicle faster!
