Wiseco BBC Quick 16 +40cc Dome 4.625in Bore 1.060inch CH Piston Shelf Stock

Forged from 2618 aluminum, this Wiseco piston is built for serious performance in Big Block Chevrolet engines. The 4.625 inch bore size and 1.060 inch compression height are key dimensions for building a specific engine combination. This piston features a 40cc dome, which is designed to work with certain cylinder head volumes to achieve a desired compression ratio for heavy to severe duty racing applications.

Wiseco includes several features for improved durability and performance. The piston crown is fully machined, and the ring grooves are precision-machined to help seal combustion gases. An ArmorGlide skirt coating is applied to reduce friction and resist seizure, contributing to quieter operation and longer life under demanding conditions. Forced pin oiling is also incorporated to ensure the wrist pin receives adequate lubrication.

This piston is sold individually, so be sure to order the correct quantity for your engine build. It's designed for builders who need robust components for high-stress race applications.
