Wiseco Chrysler Small Block 318/340/360 - 4.03in Bore -20cc Dish Top Pistons

Wiseco is well-known for making strong, reliable internal engine components, especially for high-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 built to take it.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over other materials. They feature a -20cc dish top, a 4.030-inch bore size, and a 1.460-inch compression height. You'll also find precision ring grooves, an anti-detonation groove, and other features to help improve ring seal. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The crown is also fully machined, and they include forced pin oiling to keep things well-lubricated.

This set includes 8 pistons, the pin diameter is 0.984 inches. Keep in mind these are intended for heavy to severe duty performance builds and are not CARB approved, so they cannot be shipped to California. For serious engine builders, these pistons offer a solid foundation for a powerful and durable build.
