What is the compression distance and wrist pin size for these pistons?

These JE Pistons have a compression distance of 1.100 inches and use a 0.927-inch wrist pin. This information is important for calculating your engine's compression ratio and ensuring proper piston-to-valve clearance.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design uses a reduced skirt width on the piston. This helps to minimize friction and power loss by reducing the surface area that contacts the cylinder wall, while also saving weight.

Are these pistons compatible with all 302/351 engines?

These pistons are specifically designed for 302 and 351 Windsor small block Ford engines. However, due to emissions regulations, they are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance 302 or 351 Windsor small block Ford, these JE Pistons dish-style pistons are a solid choice. JE Pistons has been making forged pistons for racing applications for over 75 years, and these are made entirely in the USA from 2618 aluminum. This material gives them the strong tensile strength needed for demanding engine builds where reliability and power are critical.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width to minimize friction and power loss. They also have a specific dish volume of -10.1 cc, designed to work with certain cylinder head combinations to achieve a desired compression ratio. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, which improves ring seal and keeps power consistent. Some applications also benefit from a skirt coating that reduces friction and noise while also cutting down on wear.

This set includes eight pistons, each with a 4.020-inch bore, a 1.100-inch compression distance, and a 0.927-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
