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

If you're building a high-performance Big Block Chevrolet engine, you need pistons that can handle the stress. These Wiseco Professional Series pistons are forged from 2618 aluminum, a well-built material chosen for its improved tensile strength under extreme conditions. They are designed for heavy to severe duty race builds where durability and consistent performance are critical.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. The crown is also fully machined for a clean, consistent surface. For added durability and reduced friction, the skirt is coated with ArmorGlide, which helps prevent seizure, lowers friction, and makes for quieter operation. The forced pin oiling design ensures the wrist pin stays well-lubricated, even under high loads.

This piston has a +15.6cc dish volume and a 1.060 inch compression height. Please note that these pistons are not CARB approved and cannot be shipped to California.
