Wiseco Chevy Small Block V8 400 Forged Pistons 4.185in Forged Dome 3.0cc 3.75in Stroke

If you're rebuilding a high-performance Chevrolet Small Block V8 400 engine for serious racing, these Wiseco Professional Series forged pistons are built to handle the demands. They're designed for applications that push the limits, offering a robust solution for heavy to severe duty builds where durability and consistent performance are critical. The 4.185-inch bore size and 3.0cc forged dome are specific to the 400ci variant, working with a 3.75-inch stroke to achieve your desired compression ratio and displacement.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, a material chosen for its improved tensile strength under extreme conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal and prevent detonation. The piston crowns are fully machined for accuracy, and they include forced pin oiling to keep the wrist pins properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all contributing to a longer-lasting, more reliable engine.

This set includes eight pistons, ready to be installed in your performance engine build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
