What is the bore size and dish volume for these pistons?

These pistons are designed for a 4.040 inch bore and feature a dish-style piston top with a -10.9cc volume. This dish volume is important for setting your compression ratio.

What material are these pistons made from and why is it important?

They are forged from 2618 aluminum, which is chosen for its high tensile strength. This material is crucial for performance engines that experience high cylinder pressures and temperatures, offering improved durability over other aluminum alloys.

Are these pistons compatible with all 302/351 engines?

These pistons are specifically designed for 302/351 Small Block Ford engines with a 4.040 inch bore. It's important to verify that this bore size matches your engine block specifications before installation.

Product Details

Forged in the USA from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is designed for 302/351 Small Block Ford engines and features a dish-style piston top with a -10.9cc volume, intended for a 4.040 inch bore. The 2618 aluminum alloy provides the high tensile strength needed to withstand the rigors of performance builds, ensuring durability when you push your engine hard.

JE Pistons incorporates their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

This piston set is made 100% in the USA and is specifically designed for each engine and use application to offer an optimized combination of performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding a performance 302 or 351 Windsor, this set offers a well-built foundation for your project.
