Wiseco BBC BIG CHIEF 3815 HEAD +15.6cc 1.060 CH Piston Shelf Stock Kit

This kit includes a set of eight Wiseco Professional Series forged pistons, designed for Chevrolet Big Block engines with a 4.600 inch bore. These pistons are built for serious racing and heavy-duty applications, featuring a +15.6cc dish volume and a 1.060 inch compression height. They are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding performance builds.

Wiseco has packed these pistons with features to handle severe duty. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The crown is fully machined, and they include forced pin oiling to keep things lubricated. A notable feature is the ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation.

Because these are intended for high-performance racing, they are not CARB approved and cannot be shipped to California. If you're building a serious race engine and need pistons that can withstand heavy use, this Wiseco set is a solid option.
