About this part

Product Details

This Manley rotating assembly includes a 4340 forged steel crankshaft, 4340 forged steel H-beam connecting rods with 7/16? ARP 8740 cap screws, and 2618 forged aluminum Platinum Series pistons with Premium Chrome Moly wrist pins. It’s designed for BBC 572 engines with a 4.250-inch stroke and 4.625-inch bore, featuring a -3cc piston dish.

The crankshaft is forged from 4340 steel, offering a solid foundation for high-stress applications. The H-beam connecting rods, also made from 4340 forged steel, are equipped with ARP 8740 cap screws, known for their strength and reliability. For those pushing the limits, optional ARP 2000 cap screws are available to handle even greater loads. The Platinum Series pistons are forged from 2618 aluminum, a material chosen for its strength and thermal expansion properties, and come with durable Premium Chrome Moly wrist pins.

This assembly is rated for up to 900 horsepower when using the standard ARP 8740 cap screws. If you plan to exceed that threshold, upgrading to the optional ARP 2000 cap screws allows the assembly to handle up to 1,500 horsepower. Please note that this assembly is not CARB approved and cannot be shipped to California. Always consult manufacturer documentation for specific installation requirements and torque specifications.
