Manley Rotating Assembly, SBC 383 3.750 STROKE/-4cc FLAT

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 kit gives you the core pieces to create a robust foundation. It includes a 3.750-inch stroke crankshaft, connecting rods, and pistons, all designed to work together for optimal performance.

The heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs. Paired with this are 4340 forged steel H-beam connecting rods. These rods are fitted with 7/16-inch ARP 8740 cap screws, a solid choice for many performance applications, with an option to upgrade to ARP 2000 cap screws for even more strength. The pistons are Manley's Platinum Series, made from 2618 forged aluminum and come with premium chrome moly wrist pins. This combination of materials and construction is built to withstand the demands of performance engines.

This rotating assembly is rated for up to 750 horsepower when using the standard ARP 8740 cap screws, and can handle an impressive 1,500 horsepower if you opt for the ARP 2000 cap screws. Please note that this assembly is not CARB approved and cannot be shipped to California. It's a well-built package for those looking to build a powerful Small Block Chevy engine.
