Manley Performance is well-known for making strong internal engine components, and this BBC 565 rotating assembly is a prime example of their commitment to building parts that can handle serious power. If you're putting together a big-block Chevrolet engine for high-performance applications, this assembly gives you the core pieces you need to build a robust powerplant.

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 are equipped with 7/16? ARP 8740 cap screws, which are rated for up to 900 horsepower. If your build aims for even more power, you can opt for ARP 2000 cap screws, which will support up to 1,500 horsepower. The assembly also includes 2618 forged aluminum Platinum Series pistons, known for their strength and heat resistance, complete with premium chrome moly wrist pins for reliable operation.

This rotating assembly is designed for builds targeting significant horsepower. Remember that this part is not CARB approved and cannot be shipped to California.
