Manley Rotating Assembly, BBC 615 4.625 STROKE/4.600/-3cc

Starting with a 4340 forged steel crankshaft, this Manley rotating assembly is built for serious BBC performance. The 4.625-inch stroke and 4.600-inch bore dimensions are designed for big-block Chevrolet engines looking to handle significant power. This assembly is a solid foundation for a high-horsepower build, capable of supporting up to 900 horsepower with the standard ARP 8740 cap screws, and an impressive 1,500 horsepower when optioned with ARP 2000 cap screws.

The included 4340 forged steel H-beam connecting rods are robust and feature 7/16-inch ARP cap screws, with the option to upgrade to ARP 2000 fasteners for even greater strength. Paired with these are Manley's Platinum Series pistons, made from 2618 forged aluminum for a good balance of strength and weight. These pistons come complete with premium chrome moly wrist pins, ensuring durability under demanding conditions. The -3cc piston dish helps achieve a specific compression ratio, making this assembly a well-considered choice for builders aiming for a particular performance target.

This rotating assembly is a significant investment for a performance engine build. It's important to note that this part is not CARB approved and cannot be shipped to California.
