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

Manley Performance is 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 high-performance engine and need a solid foundation, this package gives you the core pieces to get started. It's designed around a 3.750-inch stroke crankshaft, which is a popular choice for achieving 383 cubic inches in a standard SBC block.

This assembly includes a lightweight 4340 forged steel crankshaft, which is strong enough to handle significant power. The connecting rods are also made from 4340 forged steel in an H-beam design, known for its strength and rigidity. They come equipped with 7/16-inch ARP 8740 cap screws, a very reliable fastener for performance applications. For those pushing the limits, there's an option to upgrade to ARP 2000 cap screws for even greater clamping force. The pistons are 2618 forged aluminum from Manley's Platinum Series, featuring a +11cc dome volume and Premium Chrome Moly wrist pins. This combination of materials and design means the assembly is built to withstand the demands of performance driving.

With the included ARP 8740 fasteners, this rotating assembly is rated for up to 750 horsepower. If you opt for the ARP 2000 cap screws, that rating increases to an impressive 1,500 horsepower. This makes it a versatile choice for a wide range of performance builds, from a strong street engine to a dedicated race motor. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
