The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins, ensuring they can withstand the intense pressures and temperatures of a powerful engine. This assembly is rated for up to 900 horsepower with the standard ARP 8740 fasteners, and can support an impressive 1,500 horsepower when upgraded to ARP 2000 cap screws.

This assembly is specifically configured for a 4.625-inch stroke and a 4.600-inch bore, with -3cc dish pistons to help achieve your desired compression ratio.
