Description

The JE Pistons 280266S is a set of high-performance pistons designed for Naturally Aspirated 632 Big Block Chevy engines. These pistons feature a flat top design and are constructed from 2618 forged aluminum for high tensile strength. They are precision CNC machined with specific ring groove dimensions for optimal sealing.

Designed to fit with specific cylinder heads, including 12º Raptor, 12º Pro-Filer, Dart Big Chief 14º, Sonny Tru-Pro 14.5º, and Brodix PB1200, these pistons ensure compatibility with popular performance heads. The compression distance and ratio are calculated with zero deck clearance.
