Wiseco Chevy Big Block 4.600in Bore 1.270in CH 15.00 CC Piston Set

If you're building a high-performance Chevy Big Block engine for serious racing or severe duty applications, you need pistons that can handle the stress. This set of eight forged pistons from Wiseco is designed specifically for that purpose. They feature a 4.600-inch bore and a 1.270-inch compression height, crucial dimensions for achieving the right compression ratio and valve-to-piston clearance in your build.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under extreme conditions. Wiseco has incorporated several features to enhance performance and durability, including precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The piston crown is fully machined for a clean, consistent surface, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Additionally, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, all important factors when pushing an engine to its limits.

This set is intended for heavy to severe duty race builds where reliability and performance are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure these specifications align with your specific build goals.
