Manley Performance is well-known for making strong internal engine components, and this BBC rotating assembly is a prime example of their commitment to building parts that can handle serious power. This kit is designed for Big Block Chevy engines and features a 4.625-inch stroke with a 4.600-inch bore, and a -3cc piston dish. It’s a complete package for anyone looking to build a high-performance engine that can take a beating.

At the heart of this assembly is a 4340 forged steel crankshaft, chosen for its strength and durability under high stress. The connecting rods are also made from 4340 forged steel in an H-beam design, and they come equipped with 7/16-inch ARP 8740 cap screws, with an option to upgrade to ARP 2000 cap screws for even more strength. Paired with these are 2618 forged aluminum Platinum Series pistons, which are lightweight yet strong, and include premium chrome moly wrist pins for reliable operation. This combination is built to handle a significant horsepower range, supporting up to 900 horsepower with the standard ARP 8740 bolts and up to 1,500 horsepower when you opt for the ARP 2000 cap screws.
