Wiseco Chevy Big Block 4.605in Bore 1.170in CH 20.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders who demand strength and durability in their Chevy Big Block engines. The 4.605-inch bore size is specific for certain Big Block configurations, and the 1.170-inch compression height is a critical measurement for setting up your engine's valve timing and piston-to-head clearance. These pistons are designed for heavy to severe duty race applications where reliability under extreme stress is paramount.

Wiseco machines these pistons in the USA, incorporating features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements to ensure optimal performance and longevity. The ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, while the fully machined crown and forced pin oiling further enhance their capability for demanding builds. This set includes eight pistons, ready to be installed in your high-performance engine.

When building a race engine, attention to detail is key. These pistons are a solid choice for those looking to push their Big Block's limits. Remember that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
