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

If you're building a serious big-block Chevrolet engine, a strong rotating assembly is the heart of the operation. This Manley Performance BBC 565 rotating assembly is built for those who demand serious power and reliability from their engine. It's designed to handle the stresses of high-performance builds, providing a solid foundation for your next project.

At the core of this assembly is a 4340 forged steel crankshaft, chosen for its strength and durability under extreme loads. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a well-known choice for strength, but you can opt for ARP 2000 cap screws for even greater capability, pushing the horsepower range up to 1,500 HP. The pistons are 2618 forged aluminum from Manley's Platinum Series, complete with Premium Chrome Moly wrist pins, ensuring they can withstand the intense heat and pressure of combustion. This combination is rated for up to 900 horsepower with the standard ARP 8740 bolts, offering a significant performance upgrade for your BBC.

This assembly is a substantial upgrade for any performance BBC build. It's important to note 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 torque specifications.
