Wiseco Chevy Big Block 4.500in Bore 1.270in CH 45.00 CC Piston Set

When you're building a serious performance engine for your Chevy Big Block, you need parts that can handle the stress. This set gives you eight Wiseco Professional Series pistons, forged and machined right here in the USA from 2618 aluminum. This material is chosen for its improved tensile strength, which is crucial for pistons that will see heavy or severe duty in race applications.

These aren't just basic pistons; they're packed with features to help your engine perform and last. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are also standard on these pistons, ensuring consistent lubrication and performance under demanding conditions.

This set is designed for a 4.500-inch bore with a 1.270-inch compression height and a 45.00 CC dish volume. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For builders aiming for the highest levels of performance, these Wiseco pistons are a solid choice.
