Manley Rotating Assembly, SBC 383 3.750 STROKE/-15cc DISH

If you're building a high-performance Small Block Chevy engine and need a solid foundation, this Manley rotating assembly is a great place to start. It's designed to handle serious power, giving you the confidence to push your engine's limits. This kit centers around a 3.750-inch stroke crankshaft, creating a 383 cubic inch displacement when paired with the correct bore size, a popular choice for a balance of torque and horsepower.

Manley has put together a robust package here. The crankshaft is forged from 4340 steel, a strong material that can withstand the stresses of high RPM and significant cylinder pressures. Complementing the crank are 4340 forged steel H-beam connecting rods, known for their strength and reliability in performance applications. These rods come with 7/16-inch ARP 8740 cap screws, but you have the option to upgrade to ARP 2000 fasteners for even greater strength, allowing the assembly to handle up to 1,500 horsepower. The pistons are forged aluminum from Manley's Platinum Series, featuring a -15cc dish to help achieve your desired compression ratio, and they include premium chrome moly wrist pins for durability.

This assembly is rated for 750 horsepower with the standard ARP 8740 bolts and can be pushed to 1,500 horsepower with the optional ARP 2000 cap screws. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. You'll want to ensure you have all the necessary supporting components, such as bearings, piston rings, and a proper balancing procedure, to complete your engine build.
