Manley Rotating Assembly, BBC 632 4.750 STROKE/4.600/-3cc

If you're building a serious big-block Chevrolet engine for high-performance street or track use, a robust rotating assembly is the heart of your build. This Manley Performance rotating assembly is designed for the BBC 632ci platform, featuring a 4.750-inch stroke crankshaft and 4.600-inch bore pistons with a -3cc dish. It's a well-built foundation for engines aiming for significant power output.

The crankshaft and H-beam connecting rods are forged from 4340 steel, a strong material known for its durability under high stress. The connecting rods come standard with 7/16-inch ARP 8740 cap screws, capable of handling up to 900 horsepower. For those pushing the limits further, an option for ARP 2000 cap screws is available, which raises the horsepower ceiling to a notable 1,500 HP. The pistons are forged from 2618 aluminum, a common choice for performance applications due to its strength and thermal properties, and they include premium chrome moly wrist pins.

This assembly is a solid option for builders who need a reliable rotating assembly for a high-output BBC engine. Please note that this part is not CARB approved and cannot be shipped to California.
