The JE Pistons forged BBC eight-cylinder piston set with a 4.530 in. bore and a .415 dome (37.0 cc) is crafted for demanding domestic engine use. Made in the USA from 2618 aluminum, the pistons incorporate JE's Forged Side Relief forging to cut skirt drag; optional accumulator grooves and skirt coatings reduce ring flutter and friction, helping the rings maintain a consistent seal under load.
