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, this kit gives you the core pieces to create a robust foundation. It's designed for a 3.750-inch stroke and features pistons with an +11cc dome, which will affect your compression ratio depending on your cylinder head volume.

At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs. Paired with it are 4340 forged steel H-beam connecting rods. These rods come standard with 7/16? ARP 8740 cap screws, a solid choice for builds up to 750 horsepower. If your build aims higher, you can opt for ARP 2000 cap screws, which can support up to 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 stress.

This rotating assembly is a significant step up from stock components, offering the strength and reliability needed for demanding engine builds. Remember that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder to ensure this assembly meets your specific performance goals and compression targets.
