Wiseco Chevy Big Block 4.600in Bore 1.395in CH -8.00 CC Piston Set

When you're building a serious performance engine for your Chevy Big Block, especially for heavy or severe duty racing, the pistons are a critical component. This set from Wiseco is designed to handle extreme conditions, giving you the confidence to push your engine to its limits. They're built with a focus on both strength and performance, ensuring your engine can withstand the demands of competition.

These pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential for high-stress applications. Wiseco has included several features to enhance performance and durability, such as precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The crown of each piston is fully machined, and they come with forced pin oiling to ensure proper lubrication. Additionally, they feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly.

This set includes eight pistons, each designed for a 4.600-inch bore with a 1.395-inch compression height and a -8.00cc dish volume. They are intended for use with a 0.990-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for a high-performance build that needs to stand up to severe duty, this Wiseco piston set is a solid option.
