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

If you're building a serious big-block Chevrolet engine and aiming for serious power, a well-matched rotating assembly is the heart of the operation. This Manley Performance rotating assembly is designed for BBC applications, specifically for a 632 cubic inch displacement with a 4.750-inch stroke and a 4.600-inch bore. It’s a critical component that handles the immense forces generated when you’re pushing for high horsepower figures.

Manley has put together a solid package here. The crankshaft is forged from 4340 steel, which is a strong material chosen for its ability to withstand high stress. Complementing the crank are 4340 forged H-beam connecting rods, which come standard with 7/16-inch ARP 8740 cap screws, or you can opt for ARP 2000 fasteners for even more strength. The pistons are 2618 forged aluminum from Manley's Platinum Series, and they include premium chrome moly wrist pins. This combination is built to handle a wide range of power levels, rated for up to 900 horsepower with the standard ARP 8740 bolts, and can safely handle up to 1,500 horsepower if you choose the optional ARP 2000 cap screws. This level of robust construction means you can build a powerful engine with confidence.

When assembling an engine of this caliber, ensuring all components work together is key. This rotating assembly is a well-matched set, simplifying the process of building a high-performance BBC. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications for installation and compatibility with other engine components.
