Our Latest Twist on the Big-Torque 383 Stroker!

When it comes to cranking serious torque from the classic Small-Block, it’s hard to beat the 383 stroker combination, which uses a long, 3.800-inch stroke with 4.005-inch bores to generate exceptional low-end pulling power and surprising high-rpm horsepower.

Chevrolet Performance’s stroker crate engine is part of our range of Street Performance engines and is designed for optimal performance on the street and the occasional trip down the quarter-mile.

It features lightweight aluminum cylinder heads based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves. Beehive-style valve springs enable great high-rpm performance and durability, allowing the SP383 to rev higher and build more horsepower. The result is 435 exhilarating horsepower and 445 lb.-ft. of seat-tugging torque.

Like all of our 350-based crate engines, it is built with a cast-iron block with four-bolt mains. It also features a forged steel crankshaft, an aggressive hydraulic roller camshaft and a high-flow, aluminum intake manifold. Use the Holley 770-cfm four-barrel carburetor, P/N 19170093 to achieve the listed horsepower and torque ratings.
