Wiseco BBC Quick 8 +15.6cc 18deg 1.120inch CH Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for high-performance applications. This Professional Series piston kit is a prime example, built from the ground up for serious racers and builders who demand durability and performance. These pistons are designed to handle the rigors of heavy to severe duty race builds, removing limits so you can push your engine further.

Each piston in this set is forged and machined in the USA from 2618 aluminum, 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 crown is fully machined for accuracy, and they feature forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit in high-stress builds.

This kit includes a set of 8 pistons, each with a 4.600 inch bore and a 1.120 inch compression height. The dish volume is +15.6cc with an 18-degree valve angle, and the pin diameter is 0.990 inches. These pistons fit a wide range of Chevrolet Big Block applications, including vehicles like the 1970-1975 Chevrolet Bel Air, 1970-1972 Chevrolet Biscayne, and 1973-1980 Chevrolet C10 Suburban, among many others. Please note that these are not CARB approved and cannot be shipped to California.
