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

Manley Performance is well-known for making strong internal engine components, and this 383 cubic inch rotating assembly for Small Block Chevy engines is a prime example. If you're building a serious performance engine and need a solid foundation, this kit is designed to handle significant power. It includes everything you need to get your short block started, featuring a 3.750-inch stroke crankshaft that helps achieve the 383 displacement.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and reduced rotational mass. Paired with it are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, capable of handling up to 750 horsepower. For those pushing the limits, you have the option to upgrade to ARP 2000 cap screws, which can support an impressive 1,500 horsepower. The pistons are made from 2618 forged aluminum, part of Manley's Platinum Series, and include premium chrome moly wrist pins for durability under extreme conditions. The +11cc dome on the pistons is designed to work with specific cylinder head combinations to achieve your desired compression ratio.

This rotating assembly is a substantial investment for a performance engine build. It's important to note that this kit is not CARB approved and cannot be shipped to California. Ensure you have the correct supporting components, such as bearings, piston rings, and a balanced harmonic balancer, to complete your engine assembly. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
