Wiseco Chevy Big Block 4.615in Bore 1.120in CH 23.00 CC Piston Set

If you're rebuilding a high-performance Chevy Big Block engine for serious racing or severe duty applications, a solid set of pistons is where you start. This Wiseco Professional Series piston set is built from the ground up to handle the extreme demands of competitive racing. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress and temperature conditions.

Wiseco has packed these pistons with features that matter for racing. You'll find precision ring grooves designed for optimal sealing, along with anti-detonation grooves and other features to improve ring seal and prevent detonation. The piston crown is fully machined for accuracy, and the pistons come with forced pin oiling to ensure the wrist pin stays well-lubricated. Plus, they include an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, even under heavy load.

This set is designed for a 4.615-inch bore and features a 1.120-inch compression height, with a 23.00 CC dish volume. Remember, these pistons are not CARB approved and cannot be shipped to California. They are intended for heavy to severe duty performance builds where durability and consistent performance are critical.
