Wiseco BBC Quick 8 +15.6cc 18deg 1.155inch CH Piston Shelf Stock

This listing is for a single Wiseco Professional Series forged piston, designed for Chevrolet Big Block engines. It features a 4.600-inch bore and a 1.155-inch compression height, with a dish volume of +15.6cc that results in an 18-degree valve angle. These pistons are built from 2618 aluminum, a material chosen for its improved tensile strength, and are machined in the USA. They are intended for heavy to severe duty race builds where durability and performance are critical.

Wiseco has incorporated several features to enhance performance and longevity. The piston crown is fully machined, and it includes precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly. For added reliability, these pistons also feature forced pin oiling to ensure the wrist pin stays well-lubricated under demanding conditions. This piston fits a wide range of Chevrolet vehicles from the early 1970s through the late 1990s, including models like the Chevrolet C10 Suburban and Chevrolet Impala.
