Manley Rotating Assembly, BBC 565 4.250 STROKE/4.600/-3cc

Manley Performance is well-known for building robust engine components, and this BBC 565 rotating assembly is a prime example of their commitment to strength and reliability. If you're building a serious big-block Chevrolet engine, this assembly is designed to handle significant power. It features a 4.250-inch stroke crankshaft and is sized for a 4.600-inch bore with a -3cc piston dish, making it ideal for a 565 cubic inch displacement.

At the heart of this assembly is a 4340 forged steel crankshaft, chosen for its exceptional 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, capable of handling up to 900 horsepower. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which raises the horsepower ceiling to a stout 1,500 HP. The pistons are forged from 2618 aluminum in Manley's Platinum Series, complete with premium chrome moly wrist pins, ensuring they can withstand the demands of a high-performance engine.

This rotating assembly is a solid foundation for a powerful street or race engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures.
