Wiseco Chevy Big Block 4.350in Bore 1.645in CH 32.00 CC Piston Set

If you're building a serious performance Chevrolet Big Block engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which gives them improved tensile strength needed for heavy to severe duty race applications. They are designed to handle the demands of high-performance builds where reliability is critical.

Wiseco has packed these pistons with features to ensure top performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features that improve ring seal. The fully machined crown and forced pin oiling are also notable details. Plus, they come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, leading to quieter operation and longer life.

This set includes eight pistons, each designed for a 4.350-inch bore with a 1.645-inch compression height and a 32.00cc dish volume. Remember, these pistons are not CARB approved and cannot be shipped to California.
