Wiseco Chevy 305 3.766in Bore 1.550in CH -3.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Chevrolet 305 engines. The 3.766-inch bore size and 1.550-inch compression height, combined with a -3.00cc dish volume, are specific dimensions for certain engine builds. Wiseco machines these pistons in the USA, ensuring precise manufacturing for critical engine components.

Beyond the base material, Wiseco includes several features to enhance durability and performance. The pistons have precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by under high stress. They also feature forced pin oiling to ensure the wrist pin receives adequate lubrication, and the crown is fully machined for a clean, consistent combustion chamber surface. The ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life in demanding applications.

This set includes eight pistons, designed for heavy to severe duty race applications. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
