Wiseco Chevy Big Block 4.610in Bore 1.270in CH 28.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty engine builds. The 4.610-inch bore size is specific to certain Chevrolet Big Block applications, and the 1.270-inch compression height is a key measurement for setting up your engine's valve timing and piston-to-deck clearance. Wiseco machines these pistons in the USA, ensuring precise control over every step of the manufacturing process.

Beyond the strong aluminum construction, these pistons feature a fully machined crown for accuracy and include advanced features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements. The ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation. Forged pin oiling is also incorporated to ensure the wrist pin receives adequate lubrication under high stress.

This set includes eight pistons, designed to withstand severe duty performance applications. If you're building a high-performance or race engine for your Chevy Big Block and need pistons that can handle extreme conditions, this Wiseco Professional Series set is a solid option. Please note that these pistons are not CARB approved and cannot be shipped to California.
