Chevrolet SP383 Performance Crate Motor

For decades, Chevrolet has channeled the technology and experience from racing on road courses, ovals, and drag strips into high-performance crate engines with engineering no aftermarket manufacturer can match.  The Street Performance (SP) line of engines offers great power at a great value, and Chevrolet SP383 Performance Crate Motor Deluxe (part number 19355722) is more powerful than ever.  Power-focused engineers continue to refine the classic Chevy V8 for even greater performance and this stroked Small Block is their latest triumph.

Advanced features include 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.  A hydraulic roller camshaft with more the 0.500-inch lift optimizes the airflow enabled by the high-flow head design.  It also features a forged-steel crankshaft and durable, high-silicon pistons.

Unique valve covers distinguish this engine from previous versions of the SP383, and it now includes a high-flow, aluminum intake manifold.  Chevrolet Performance’s engineers recommend you use the Holley 770-cfm four-barrel carburetor (P/N 19170093) to make the most of the SP383’s capability and achieve the listed horsepower and torque ratings.

Chevrolet Performance pioneered the crate engine concept nearly 50 years ago and has never stopped working to build stronger engines that offer performance and value.  You can trust Chevy Performance crate motors and components when it comes to your next project.
