About this part

Product Details

When you're building a serious big-block Chevrolet engine, the rotating assembly is the heart of the operation. This Manley Performance rotating assembly gives you the core components needed for a powerful build. You get a 4340 forged steel crankshaft, a set of 4340 forged steel H-beam connecting rods, and a set of 2618 forged aluminum pistons. This package is designed for BBC (Big Block Chevrolet) engines and features a 4.375-inch stroke with a 4.600-inch bore and +43cc piston dish volume.

The crankshaft and connecting rods are made from strong 4340 forged steel, a material known for its durability under high stress. The H-beam connecting rods come standard with 7/16-inch ARP 8740 cap screws, which are suitable for builds up to 900 horsepower. If your build demands more, you have the option to upgrade to ARP 2000 series cap screws, allowing the assembly to handle up to 1,500 horsepower. The included 2618 forged aluminum pistons are part of Manley's Platinum Series, known for their robust construction, and they come with premium chrome moly wrist pins for added strength and reliability.

This assembly is intended for high-performance applications and is not CARB approved, meaning it cannot be shipped to California. It's a solid foundation for a custom engine build where power and reliability are key considerations.
