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 assembly is designed to handle significant power. It includes a crankshaft, connecting rods, and pistons, all engineered to work together as a balanced unit for your engine build.

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, a solid choice for many performance applications. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws, which can support up to 1,500 horsepower. The pistons are 2618 forged aluminum from Manley's Platinum Series, featuring a +11cc dome and Premium Chrome Moly wrist pins. This combination is built to withstand the demands of high-performance engines, with the standard ARP 8740 hardware rated for up to 750 horsepower.

This rotating assembly is a crucial starting point for a high-output engine. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to Manley's detailed specifications for proper installation and balancing procedures to achieve the best results for your specific build.
