JE Pistons BBC FT HD/BLOWN Set of 8 Pistons

When you're building a big block Chevy engine for serious performance, especially one that's going to see forced induction or a blower, the pistons are a critical component. This set of eight pistons from JE Pistons is designed to handle the extra stress and heat that comes with those high-demand applications. They're forged in the USA from 2618 aluminum, a material known for its strength, which is exactly what you need when you're pushing an engine hard.

JE Pistons has been around for a long time, and they've put that experience into these pistons. They feature a proprietary Forged Side Relief (FSR) design, which means they've worked to minimize friction and power loss by using a slightly narrower skirt and a shorter wrist pin, saving weight in the process. Depending on your specific engine setup, these pistons might also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also get a skirt coating that further reduces friction and wear, helping to quiet things down and extend the life of the piston and cylinder wall.

This particular set is for a 4.310-inch bore with a flat top design and a -3.0cc dish, and they use a 0.990-inch wrist pin. It's important to note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance big block Chevy, these JE Pistons are a solid choice to form the foundation of your engine.
