Wiseco 4.630 Big Block Chevy Quick 16 +42cc Dome 1.120CH Piston Set

If you're building a high-performance Big Block Chevy engine for serious racing or heavy-duty applications, these Wiseco Professional Series pistons are a solid choice. They're designed to handle the extreme demands of severe duty builds, offering a significant step up from stock components. With a 4.630-inch bore and a +42cc dome, these pistons are engineered to work with specific compression ratios for maximum power output in racing scenarios.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength to withstand the high pressures and temperatures found in race engines. You'll find precision ring grooves, anti-detonation grooves, and features designed for better ring seal, all contributing to reliable performance under stress. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a notable detail for longevity in demanding builds. The fully machined crown and forced pin oiling further enhance their durability and performance capabilities.

This set includes eight pistons, ready for your next 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 procedures.
