Manley Rotating Assembly, BBC 565 4.250 STROKE/4.600/+43cc

Starting with a 4340 forged steel crankshaft is key for any serious BBC build. This Manley rotating assembly is designed for big-block Chevrolet engines, specifically configured for a 565 cubic inch displacement with a 4.250-inch stroke and 4.600-inch bore. The crankshaft is forged from 4340 steel, a material known for its strength and durability under extreme stress, making it a solid foundation for high-performance applications.

Complementing the crankshaft are the 4340 forged steel H-beam connecting rods. These rods are equipped with 7/16-inch ARP 8740 cap screws, a well-regarded fastener for reliability. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which significantly increases the horsepower range this assembly can handle. The pistons are crafted from 2618 forged aluminum, part of Manley's Platinum Series, and come with Premium Chrome Moly wrist pins. This combination of materials and robust construction is built to withstand the demands of powerful engines.

This assembly is rated for up to 900 horsepower with the standard ARP 8740 fasteners, and can safely handle up to 1,500 horsepower when equipped with the optional ARP 2000 cap screws. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder to ensure this rotating assembly meets the specific requirements of your build.
