Wiseco Chrysler Small Block V8 318/340/360 -20cc R/Dome

When you're building a serious performance engine for your Chrysler Small Block V8, you need parts that can handle the stress. This set includes eight forged pistons from Wiseco, designed for 318, 340, and 360 cubic inch engines with a 4.040 inch bore. These pistons feature a -20cc reverse dome, which is crucial for achieving specific compression ratios in your build.

Wiseco makes these pistons from 2618 aluminum right here in the USA, chosen for its improved tensile strength under high loads. They've got precision-machined ring grooves, anti-detonation grooves, and other features to ensure a solid seal and prevent detonation. You'll also find an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The fully machined crown and forced pin oiling are details that show these are built for the long haul in demanding race applications.

This set is intended for heavy to severe duty race builds, so if you're pushing your engine hard, these are a solid option. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
