What is the bore size and pin diameter for these pistons?

These pistons have a 4.030 inch bore and come with a 0.927 inch pin. This sizing is important for matching with your cylinder block and connecting rods.

What are the benefits of the Forged Side Relief (FSR) design?

The FSR design helps to minimize friction and power loss by reducing the piston skirt width. It also saves weight with a shorter wrist pin, contributing to overall engine performance.

Are these pistons compatible with all 350/400 SBC engines?

These pistons are designed for 350/400 Small Block Chevy engines. However, due to their performance nature and specific design features, it's recommended to verify compatibility with your specific engine build, including cylinder heads and camshaft, and to consult JE Pistons' technical specifications.

Depending on the specific application, these pistons may also incorporate features like a proprietary Forged Side Relief (FSR) design to minimize friction and power loss, an accumulator groove to improve ring seal, and a skirt coating to reduce friction and noise.
