What is the bore size and pin size for these pistons?

These pistons have a 4.030 inch bore and use a 0.927 inch wrist pin. The accumulator groove and skirt coating depend on the specific application.

Are these pistons suitable for a stock 351 Windsor engine?

These are performance-oriented pistons forged from 2618 aluminum, designed for high-demand applications. While they can be used in a performance build of a 351 Windsor, they are not intended as a direct replacement for stock, mild engines.

Can these pistons be shipped to California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

If you're building a high-performance 351 Windsor (SBF) engine, you need pistons that can handle the stress. This set of eight forged pistons from JE Pistons is designed specifically for these demanding applications, offering a solid foundation for serious power. They're made from 2618 aluminum, a material known for its high tensile strength, which is crucial when you're pushing an engine hard.

JE Pistons has been in the game for over 75 years, and they put that experience into these pistons. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and ensure a consistent seal for reliable power. Some applications also include a skirt coating to further reduce friction and wear, which can also quiet down the engine operation.

These pistons are forged and machined entirely in the USA, ensuring they meet strict manufacturing standards. They're a flat-top design with a 4.030-inch bore and a 0.927-inch pin size. Keep in mind that these are not CARB approved and cannot be shipped to California. If you're aiming for serious performance with your 351 Windsor, this set of pistons is a well-built choice.
