Wiseco BBC BIG CHIEF 3815 HEAD +15.6cc 4600B Piston Shelf Stock

This listing is for a single Wiseco BBC BIG CHIEF 3815 forged piston. It's built for a 4.600 inch bore and includes a +15.6cc dish volume, designed for specific compression ratios in Big Block Chevrolet engines. This piston is part of Wiseco's Professional Series, meaning it's constructed from 2618 aluminum for improved tensile strength, making it well-suited for heavy-duty performance builds.

You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The piston crown is fully machined for accuracy, and it incorporates forced pin oiling to ensure the wrist pin stays well-lubricated under stress. Additionally, it comes with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. These pistons are forged and machined in the USA.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's designed for severe duty race applications, so it's a solid option if you're building a high-performance engine that needs to handle significant stress.
