The JE forged eight-cylinder piston kit for 454 big-block Chevrolet applications pairs race-focused geometry with robust materials. Forged in the USA from 2618 aluminum, these nitrous-dome pistons fit a 4.625 in. bore with 1.270" pin sizing and a 45.0 cc dome volume. JE's FSR forging minimizes skirt width and friction while accumulator groove and skirt coating options improve ring seal under high combustion pressures.
