SP383 Deluxe 383ci Small Block Crate Motor Engine 435 HP

SKU: 19355722

Quick Overview

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 or 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!
