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

If you're building a high-performance Small Block Chevy engine and need a solid foundation, this Manley rotating assembly is a serious contender. It's designed to handle significant power, making it a great choice for street/strip applications or dedicated race engines where reliability under stress is key. This assembly centers around a 3.750-inch stroke crankshaft, creating a 383 cubic inch displacement when paired with the correct bore size.

At the heart of this package is a Manley 4340 forged steel crankshaft, known for its strength and durability under high loads. Complementing the crank are 4340 forged steel H-beam connecting rods. These rods come standard with ARP 8740 cap screws, capable of handling up to 750 horsepower, but can be upgraded with optional ARP 2000 fasteners for an increased capacity of up to 1,500 horsepower. The pistons are Manley's Platinum Series, made from 2618 forged aluminum and include premium chrome moly wrist pins, ensuring they can withstand the rigors of a powerful engine.

This assembly is a significant upgrade over stock components, providing the robust construction needed for boosted or high-RPM applications. Remember that this assembly is not CARB approved and cannot be shipped to California. Ensure you have the correct supporting components, such as pistons, rings, bearings, and a balanced harmonic balancer, to complete your engine build.
