What is the dome volume for these pistons?

These pistons have a 13.5 cc dome volume. This contributes to the compression ratio of your engine build.

Are these pistons suitable for a naturally aspirated engine?

Yes, these pistons are forged from 2618 aluminum and feature designs like FSR and optional accumulator grooves and skirt coatings that are beneficial for high-demand performance applications, including naturally aspirated builds.

What is the significance of the 2618 aluminum material?

2618 aluminum is chosen for its high tensile strength and ductility, making it well-suited for high-performance and racing applications where pistons experience significant stress and heat.

Product Details

If you're building a high-performance 350 Small Block Chevy, these JE Pistons are a solid choice. This set includes eight pistons designed to handle the demands of serious engine work, whether it's for the drag strip or a powerful street machine. They're forged in the USA from 2618 aluminum, a material known for its high tensile strength, which is crucial for engines pushing the limits.

JE Pistons has been around for over 75 years, and they've put that experience into these pistons. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and keeping power consistent. Some applications also get a skirt coating that further reduces friction and wear, while also helping to quiet down the engine operation.

This kit is for a 4.040 inch bore with a .450 inch dome height, and it includes the necessary 0.927 inch pins. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
