What is the bore size and dome volume for this piston set?

This set is designed for a 4.000 inch bore. The dome volume is 13.5 cc, which is suitable for many performance 350 SBC applications.

Are these pistons suitable for a stock 350 engine?

While these pistons are built for performance, they are designed for modified 350 SBC engines. The dome volume and forged construction are intended for builds that exceed stock specifications. It's best to consult with your engine builder to ensure they fit your specific build goals.

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

The FSR design helps minimize friction and power loss by reducing the piston skirt width. This, along with a shorter wrist pin, also contributes to saving weight on the rotating assembly.

Product Details

If you're rebuilding a classic 350 Small Block Chevy engine and pushing its performance limits, a solid set of pistons is crucial. This set of eight dome pistons from JE Pistons is built to handle the demands of a performance build, offering a strong foundation for your engine's power and durability.

JE Pistons uses a proprietary forged side relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, combined with a shorter wrist pin, also saves weight. The pistons are forged in the USA from 2618 aluminum, a material known for its high tensile strength, making them well-suited for high-demand performance applications. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, which helps prevent ring flutter and improve ring seal for consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is designed specifically for the 350 SBC engine with a 4.000-inch bore and a 13.5cc dome volume, intended to work with a 0.927-inch pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a performance-oriented rebuild, this JE Pistons set offers a well-built and proven option.
