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

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for handling the extreme pressures and temperatures found in high-performance or racing engines.

What is the Forged Side Relief (FSR) design?

The FSR design incorporates a reduced skirt width and a shorter wrist pin. This construction helps to minimize friction and power loss, while also contributing to overall weight savings for improved engine response.

Are these pistons compatible with all 350 engines?

This set is specifically designed for 350 Small Block Chevy engines with a 4.040 inch bore. It's important to confirm your engine's bore size and application requirements before installation.

Product Details

Starting with the 2618 aluminum construction, these JE Pistons are built for serious performance in your 350 Small Block Chevy. This material choice is key because it offers the high tensile strength needed when you're pushing an engine hard, whether that's on the track or just for spirited street driving. They're forged and machined entirely here in the USA, meaning you're getting a well-built part with a focus on durability and performance.

JE Pistons has incorporated their proprietary Forged Side Relief (FSR) design. This isn't just about looks; it means the skirt width is reduced and the wrist pin is shorter, which helps minimize friction and power loss while also saving weight. Depending on your specific application, you might also find an accumulator groove, which helps control combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear, keeping your engine running smoothly and quietly.

This set is designed specifically for the 350 SBC engine with a 4.040 inch bore. It includes eight flat-top pistons, each with a -5.0 cc dish, a 1.000 inch compression distance, and a 0.927 inch wrist pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding your top end for high-demand use, this set is a solid option backed by JE Pistons' extensive experience.
