Wiseco Chevy Big Block 4.605in Bore 1.155in CH 28.00 CC Piston Set

If you're building a serious performance Chevy 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're designed for builders who are pushing their engines to the limit and need components that can handle extreme stress.

Wiseco packs a lot of performance features into these pistons. You'll find precision ring grooves, anti-detonation grooves, and other features to improve ring seal, which is crucial for both power and longevity. The fully machined crown ensures consistent combustion chamber volume, and the forced pin oiling helps keep the wrist pins lubricated under high loads. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and quiet down operation.

This set includes eight pistons, each designed for a 4.605-inch bore with a 1.155-inch compression height and a 28.00cc dish volume. While these are built for serious racing, remember they are not CARB approved and cannot be shipped to California. For builders who demand durability and performance, these Wiseco pistons are a well-built option.
