Forged from domestic 2618 alloy, these Manley Performance pistons are built for serious Chevrolet big block builds. The 4.600-inch bore size and 1.058-inch compression height are key dimensions for achieving your desired compression ratio, with a 43.00 CC combustion chamber volume specified here. Professional engine builders and tuners trust Manley for the strength and durability needed to handle demanding performance applications.

Manley's design incorporates proven cam and barrel skirt profiles, which help generate substantial power while minimizing wear on your cylinder walls. They pay close attention to the details that matter for engine sealing, adhering to strict standards for piston ring lands and grooves.
