Wiseco BBC inchQ16inch Heavy NOS +42cc 1.120inch CH Piston Shelf Stock Kit

If you're building a serious performance engine for your Chevrolet Big Block, these Wiseco Professional Series pistons are a solid option. Designed for heavy to severe duty applications, they're built to handle the demands of racing and high-stress builds. This set is for an 8-cylinder engine with a 4.560 inch bore and a 1.120 inch compression height, featuring a +42cc dish to help achieve your desired compression ratio.

Wiseco makes these pistons in the USA from 2618 aluminum, which offers improved tensile strength for durability under extreme conditions. They come with precision ring grooves, anti-detonation grooves, and other features to improve ring seal. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures a clean surface for combustion.

This piston set is designed to fit a wide range of Chevrolet vehicles, including models like the C10 Suburban, Impala, and Corvette from the 1970s and 1980s, as well as later C/K series trucks and Express vans. They feature forced pin oiling for better lubrication of the wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
