This Manley rotating assembly for a BBC 572 engine includes a 4340 forged steel crankshaft, 4340 forged steel H-beam connecting rods fitted with 7/16? ARP 8740 cap screws, and 2618 forged aluminum Platinum Series pistons complete with Premium Chrome Moly wrist pins. This is a well-built package designed for serious engine builds where strength and reliability are paramount.

The crankshaft is forged from 4340 steel, a material known for its exceptional strength and durability, making it suitable for high-performance applications.

These rods come standard with ARP 8740 cap screws, capable of handling up to 900 horsepower. For those pushing the limits, optional ARP 2000 cap screws are available, increasing the horsepower range to an impressive 1,500.

The pistons are crafted from 2618 forged aluminum, a popular choice for performance applications due to its strength and ability to withstand high temperatures and pressures. They are part of Manley's Platinum Series and include Premium Chrome Moly wrist pins for added durability. This assembly is intended for builders looking for a robust foundation for a high-output big block Chevrolet engine.
