Manley rotating assembly for BBC 598 (4.500 stroke / 4.600 / +43cc). Built as a complete, matched assembly, it pairs a precision-forged crank with 4340 H-beam rods and 2618 forged Platinum Series pistons to handle extreme RPM and cylinder pressure. Premium chrome-moly wrist pins and a 4340 forged crankshaft improve durability and reduce friction, while ARP 8740 or optional ARP 2000 cap screws allow higher load capacity and elevated horsepower potential.
