Product Details
This Manley Performance rotating assembly is built for SBC (Small Block Chevrolet) engines looking to achieve a 383 cubic inch displacement with a 3.750-inch stroke. It's a well-built package designed for serious engine builds where reliability and performance are key. The -15cc dish in the pistons is a notable detail that helps achieve a specific compression ratio when paired with your chosen cylinder heads.
At the heart of this assembly is a lightweight 4340 forged steel crankshaft, chosen for its strength and ability to handle high RPMs. The connecting rods are also made from 4340 forged steel in an H-beam design, known for its robust construction. These rods come equipped with 7/16? ARP 8740 cap screws, a solid choice for many performance applications. If your build demands even more, there's an option to upgrade to ARP 2000 cap screws for increased strength. The pistons are 2618 forged aluminum from Manley's Platinum Series, which are paired with Premium Chrome Moly wrist pins for durability. This combination is rated to handle up to 750 horsepower with the standard ARP 8740 bolts, and an impressive 1,500 horsepower when using the optional ARP 2000 cap screws.
When assembling this rotating assembly, ensure you follow manufacturer guidelines for proper balancing and installation. This kit is intended for off-road use and is not CARB approved, meaning it cannot be shipped to California. It's a substantial component for anyone rebuilding or building a high-performance engine from the ground up.
