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

Starting with a 4340 forged steel crankshaft is key for this Manley rotating assembly. This material choice is a strong foundation for any high-performance Small Block Chevy build, especially when you're aiming for serious power. The 3.750-inch stroke is designed to increase displacement to a 383 cubic inch for your SBC, offering a notable bump in torque and horsepower potential over stock configurations.

Complementing the crankshaft are 4340 forged steel H-beam connecting rods. These rods are built to handle significant stress, and they come ready for either ARP 8740 or optional ARP 2000 cap screws, allowing you to tailor the assembly's strength to your horsepower goals. With ARP 8740 screws, this assembly is rated for up to 750 horsepower, while the upgrade to ARP 2000 screws pushes that capability up to an impressive 1,500 horsepower. The included 2618 forged aluminum Platinum Series pistons are lightweight yet strong, featuring a +11cc dome to help achieve your desired compression ratio. They also come with premium chrome moly wrist pins for added durability.

This assembly is a well-built package for builders looking to significantly upgrade their Small Block Chevy's engine. Keep in mind that this specific assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer documentation for complete installation guidelines and recommended supporting components to achieve optimal performance and longevity.
