Manley Rotating Assembly, BBC 572 4.250 STROKE/4.625/+43cc

If you're building a serious big-block Chevrolet engine, especially for a 572ci displacement, a strong rotating assembly is the heart of the operation. This Manley rotating assembly is designed to handle significant power, giving you a solid foundation for a high-performance build. It includes a forged steel crankshaft, forged steel connecting rods, and forged aluminum pistons, all chosen for their strength and reliability under demanding conditions.

The crankshaft is made from 4340 forged steel, a material known for its toughness and ability to withstand high stress. Paired with this are 4340 forged steel H-beam connecting rods. These rods come with 7/16? ARP 8740 cap screws, which are robust enough for up to 900 horsepower. If your build is targeting even higher output, you can opt for ARP 2000 cap screws, allowing the assembly to handle up to 1,500 horsepower. The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins, ensuring they can handle the heat and pressure of powerful combustion.

This assembly is specifically configured for a 4.250-inch stroke and a 4.625-inch bore with a +43cc piston dish. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a well-built package for those serious about maximizing the performance of their BBC engine.
