Manley Rotating Assembly, SBC 383 3.750 STROKE/+11cc DOME

If you're building a serious Small Block Chevy engine and need a solid foundation for big power, a complete rotating assembly like this one from Manley Performance is a smart way to go. This kit is designed for a 383 cubic inch displacement with a 3.750-inch stroke, giving you the displacement and leverage needed for significant horsepower gains. It’s a comprehensive package that ensures all the critical internal components are matched and ready for assembly.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs and significant stress. Paired with this are 4340 forged steel H-beam connecting rods. These rods are well-built and come standard with 7/16? ARP 8740 cap screws, but you have the option to upgrade to ARP 2000 cap screws for even greater strength, allowing the assembly to handle up to 1,500 horsepower. The pistons are Manley's own 2618 forged aluminum Platinum Series, complete with premium chrome moly wrist pins, designed to work seamlessly with the rods and crank for optimal performance and durability.

This Manley rotating assembly is engineered to support builds ranging from 750 horsepower with the standard ARP 8740 bolts up to an impressive 1,500 horsepower when opting for the ARP 2000 cap screws. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Ensure you have all necessary supporting components, such as a compatible block, cylinder heads, camshaft, and fuel system, to achieve your desired power output.
