About this part

Product Details

This is a balanced rotating assembly from Eagle, specifically built for Chevy 396 engines. It's designed for street applications running on pump gas and is naturally aspirated, meaning it doesn't use a turbocharger or supercharger. A rotating assembly is the heart of your engine's power generation, consisting of the crankshaft, connecting rods, and pistons that all work together to convert combustion pressure into rotational force.

Eagle has put together a solid package here. You get a 4.000-inch cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are strong and come with 7/16-inch ARP 8740 bolts, which are well-known for their reliability in performance applications. The pistons are Hypereutectic KB units with a 17cc closed chamber dome, designed for a 4.125-inch bore. They also include plasma-moly file-fit rings, giving you flexibility during installation to achieve a proper seal. To complete the assembly, King SI rod and main bearings are included, offering good performance for street use.

This assembly is balanced from the factory, which is a crucial step for smooth engine operation and longevity, especially when you're pushing an engine harder than stock. Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's a well-built option for someone rebuilding or upgrading their Chevy 396 for street performance.
