Product Details
Manley Performance is well-known for building serious engine components for racing and high-performance applications. This rotating assembly is a prime example, designed to give your Small Block Chevy engine a solid foundation for significant power increases. It's a complete package for building a robust 383 cubic inch stroker engine, featuring a 3.750-inch stroke and -15cc dish pistons that work together to achieve that displacement.
At 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 come standard with 7/16? ARP 8740 cap screws, a strong choice for many builds, but can be optioned with ARP 2000 cap screws for even greater reliability under extreme stress. The pistons are Manley's own Platinum Series, made from 2618 forged aluminum for durability and featuring Premium Chrome Moly wrist pins. This combination is built to handle serious power, rated for up to 750 horsepower with the standard ARP 8740 bolts and an impressive 1,500 horsepower when upgraded to ARP 2000 cap screws.
This rotating assembly is a substantial upgrade for anyone looking to build a high-output Small Block Chevy. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult with your engine builder to ensure this assembly meets your specific build requirements and local emissions regulations.
