Wiseco BBC BIG CHF 3815 HEAD +15.6cc (6421B125) Piston Shelf Stock Kit

If you're building a high-performance Big Block Chevrolet engine for serious racing or severe duty, these Wiseco Professional Series pistons are a solid choice. They're designed to handle the extreme demands of competition, offering improved tensile strength and durability thanks to their construction from 2618 aluminum. This material is well-known for its ability to withstand high temperatures and pressures found in racing applications.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and extra ring seal enhancements. These elements work together to ensure a tight seal between the piston and cylinder wall, which is critical for maximizing power and preventing blow-by under heavy load. The fully machined crown and forced pin oiling further contribute to the overall performance and longevity of the engine. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even in demanding conditions.

This kit includes a set of 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.
