Wiseco Chevy Big Block 4.600in Bore 1.170in CH 20.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine for serious racing, this Wiseco Professional Series piston set is designed to handle the demands. These pistons are specifically made for a 4.600-inch bore and feature a 1.170-inch compression height with a 20.00cc dish volume, making them a solid choice for many performance builds.

Wiseco crafts these pistons from 2618 aluminum, which offers improved tensile strength for durability under extreme conditions. They are forged and machined in the USA, ensuring precise manufacturing. You'll find features like precision ring grooves, an anti-detonation groove, and additional ring seal improvements to help maintain compression and prevent blow-by. The fully machined crown and forced pin oiling are also notable details that contribute to their robust design for heavy to severe duty applications. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure.

This set includes eight pistons, designed to be a direct replacement for your existing Big Block pistons when rebuilding or upgrading your engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
