Manley Rotating Assembly, BBC 632 4.750 STROKE/4.600/+43cc

If you're building a serious big-block Chevrolet engine for high-horsepower applications, a robust rotating assembly is the heart of your build. This Manley Performance rotating assembly is designed for BBC (Big Block Chevrolet) engines, specifically configured for a 632 cubic inch displacement with a 4.750-inch stroke and 4.600-inch bore. It's a well-built foundation that can handle significant power, making it a popular choice for drag racing, serious street performance, or any application where raw power is the goal.

At its core is a 4340 forged steel crankshaft, chosen for its strength and durability under extreme stress. Paired with this are 4340 forged steel H-beam connecting rods, which are known for their solid construction. These rods come equipped with 7/16-inch ARP 8740 cap screws, a reliable choice for many high-performance builds. For even greater strength and the ability to handle more horsepower, optional ARP 2000 cap screws are available. The assembly also includes 2618 forged aluminum Platinum Series pistons, a material selected for its lightweight properties and ability to withstand high temperatures and pressures. These pistons come with premium chrome moly wrist pins for added durability. This combination is rated for up to 900 horsepower with the standard ARP 8740 cap screws, and can support up to 1,500 horsepower when using the optional ARP 2000 cap screws.

When assembling an engine of this caliber, attention to detail is crucial. Ensure you follow the manufacturer's recommended clearances and torque specifications for all components. This assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's important to note that this is a performance part and requires proper engine building knowledge for installation.
