Wiseco Ford 302/351 Windsor -9cc Pistons

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Ford 302 and 351 Windsor engines. The -9cc dish volume is a specific design choice that helps achieve a desired compression ratio when paired with specific cylinder heads and crankshafts, making them a key component for builders aiming for a particular engine tune. Wiseco machines these pistons in the USA, ensuring precision in every detail.

You'll find features like precision ring grooves, anti-detonation grooves, and additional ring seal improvements designed to handle the demands of heavy to severe duty racing applications. The crown is fully machined for accuracy, and forced pin oiling helps keep the wrist pins lubricated under extreme conditions. A notable feature is the ArmorGlide skirt coating, which is applied to reduce friction, resist seizure, and contribute to quieter operation, even in high-stress builds.

This set includes eight pistons, each with a 4.125-inch bore and a 1.280-inch compression height, utilizing a 0.927-inch pin diameter. While these pistons are built for robust performance, please note they are not CARB approved and cannot be shipped to California. They are a solid option for anyone rebuilding or upgrading their Windsor engine for competitive use or demanding street applications.
