Wiseco Chevy Big Block 4.600in Bore 1.270in CH 28.00 CC Piston Set

If you're building a high-performance Chevrolet Big Block engine, this Wiseco Professional Series piston set is designed to handle serious power. These pistons are made for a 4.600-inch bore and feature a 1.270-inch compression height with a 28.00 CC dish volume. Wiseco crafts these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine applications.

Wiseco puts a lot of thought into the details that make a difference for racing. You'll find precision ring grooves, anti-detonation grooves, and features specifically designed to improve ring seal, all contributing to better combustion efficiency and durability. The piston crowns are fully machined for a clean, consistent surface, and they come with forced pin oiling to ensure the wrist pin stays well-lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction and noise while also resisting seizure, which is a common concern in demanding builds.

This set includes eight pistons, rings, and wrist pins, ready for installation in your heavy to severe duty race engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders focused on maximum performance and reliability in extreme conditions, this Wiseco set is a well-built option.
