The new HYPERDRYVE line of pistons is composed of a space-

age hypereutectic aluminum alloy developed by NASA. Engineered to maintain its high tensile strength up to 700 F(370C), 50% higher than a conventional cast piston, this gives HYPERDRYVE the strength to perform under operating conditions normally reserved for forged pistons.
