A 383 stroker engine, a popular modification for small-block Chevy V8s, derives its name from the increased crankshaft stroke, resulting in a larger displacement than the standard 350 cubic inches. This modification typically involves combining a 400 cubic inch crankshaft with a 350 cubic inch engine block. The power output of a 383 stroker varies significantly depending on factors like cylinder heads, camshaft profile, intake manifold, carburetor or fuel injection system, and exhaust system. A mild street build might produce between 330 and 350 horsepower, while a more aggressive racing engine could generate upwards of 500 horsepower, and even exceed 600 horsepower with optimized components and forced induction.
The popularity of the 383 stroker stems from its ability to deliver substantial increases in torque and horsepower without requiring extensive modifications to the existing engine block. This translates to significant improvements in acceleration and overall performance, making it a cost-effective upgrade for enthusiasts seeking more power. Historically, hot-rodders and racers favored this modification for its balance of power, reliability, and relative ease of implementation, leading to its enduring presence in the automotive performance landscape.
