About this part

Product Details

If you're building a serious big-block Chevrolet engine, a strong rotating assembly is the heart of the operation. This Manley Performance rotating assembly is designed for the 572 cubic inch platform, featuring a 4.250-inch stroke and a 4.625-inch bore. It's the foundation for an engine that can handle significant power, whether you're aiming for a street-strip monster or a dedicated race machine.

At its core is a 4340 forged steel crankshaft, chosen for its strength and durability under high stress. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16-inch ARP 8740 cap screws, a well-known name in high-strength fasteners, capable of handling up to 900 horsepower. For those pushing the limits even further, there's an option to upgrade to ARP 2000 cap screws, which raises the horsepower ceiling to a robust 1,500 HP. The assembly also includes 2618 forged aluminum Platinum Series pistons, known for their thermal stability and strength, complete with premium chrome moly wrist pins for reliable operation.

This rotating assembly is a substantial investment in your engine build. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder to confirm this assembly meets your specific build requirements and local emissions regulations.
