About this part

Product Details

This is the Manley Performance BBC 565 rotating assembly, built for serious big-block Chevy builds. It features a 4.250-inch stroke and is designed to work with pistons that have a +43cc volume, making it a solid foundation for a 565 cubic inch engine. If you're looking to build a powerful engine for racing or high-performance street use, a well-balanced rotating assembly like this is crucial for reliability and power delivery.

At the heart of this assembly is a 4340 forged steel crankshaft, chosen for its strength and durability under high stress. Paired with it are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16-inch ARP 8740 cap screws, which are rated for up to 900 horsepower. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, increasing the horsepower handling capability to a robust 1,500 HP. The pistons are forged from 2618 aluminum, part of Manley's Platinum Series, and include premium chrome moly wrist pins, ensuring they can withstand the intense pressures and temperatures of a high-output engine.

This assembly is a well-built package for engine builders aiming for significant power. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure all components are compatible with your specific build goals and supporting modifications.
