About this part

Product Details

This Manley Performance rotating assembly is built for SBC 383ci (cubic inch) engines with a 3.750-inch stroke and +11cc dome pistons. It’s a well-built package designed to handle serious power, whether you’re building a street machine or a dedicated race engine. A rotating assembly is the heart of your engine, consisting of the crankshaft, connecting rods, and pistons, all working together to convert combustion pressure into rotational force.

At its core is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to withstand high RPMs and significant stress. Paired with this are 4340 forged steel H-beam connecting rods. These rods are known for their robust design and come ready to accept either ARP 8740 cap screws for builds up to 750 horsepower, or optional ARP 2000 cap screws for those pushing up to 1,500 horsepower. The pistons are Manley's Platinum Series, made from 2618 forged aluminum for durability and featuring Premium Chrome Moly wrist pins for reliable operation under load.

This assembly is a solid option for builders looking for a high-performance foundation for their SBC engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
