About this part

Product Details

Manley Performance has a solid reputation for making well-built engine components for demanding applications. This rotating assembly is designed for a Small Block Chevrolet (SBC) engine, building it out to a 383 cubic inch displacement with a 3.750-inch stroke. This larger displacement can help improve torque and overall power output.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle higher RPMs. Paired with this are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a strong choice for many performance builds. If you're looking to push the limits, optional ARP 2000 cap screws are available for even greater strength, allowing for up to 1,500 horsepower. The assembly also includes 2618 forged aluminum Platinum Series pistons, known for their durability and heat resistance, complete with premium chrome moly wrist pins.

This rotating assembly is rated for up to 750 horsepower with the standard ARP 8740 cap screws, and up to 1,500 horsepower when opting for the ARP 2000 cap screws. Please note that this part is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure all components are compatible with your specific build goals and supporting modifications.
