Wiseco Chrysler Small Block 318/340/360 - 3.940in Bore -6cc Flat Top Pistons

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for Chrysler small block engines like the 318, 340, and 360. If you're building a serious performance engine that needs to handle heavy or severe duty, these pistons are engineered to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these are built for serious performance and durability.

This set includes eight pistons, each with a 3.940-inch bore and a -6cc flat top dish. The compression height is 1.460 inches, and they use a 0.984-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
