Wiseco Ford 302/351 Windsor Flat Top 4.040in Bore -7.5cc Dish Piston Shelf Stock Kit

Starting with a 2618 aluminum forging, these Wiseco pistons are built for serious performance in Ford 302 and 351 Windsor engines. The 4.040-inch bore size and -7.5cc dish volume are specific choices for certain build profiles, aiming for a particular compression ratio when paired with your cylinder heads and gasket thickness. These aren't just off-the-shelf parts; they're designed for heavy to severe duty race applications where durability and consistent performance are critical.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. They also include a forced pin oiling feature to ensure the wrist pin stays well-lubricated under high stress. The crown is fully machined, and the skirt is coated with ArmorGlide, which helps reduce friction and resist seizure, all contributing to a quieter and more durable engine operation.

This kit includes everything you need to outfit an 8-cylinder engine with these performance pistons. Remember, these are intended for racing and performance builds and are not CARB approved, so they cannot be shipped to California. Always consult your engine builder or a trusted professional to ensure these pistons are the right choice for your specific project goals.
