Eagle Chevy Big Block Rotating Assembly with 4.280in Bore 4.250in Stroke +3cc Dome

This is a balanced rotating assembly from Eagle, built for Chevy big block engines, specifically designed for applications like the 502ci. It includes a forged 4340 crankshaft with a 4.250-inch stroke, H-beam connecting rods that are 6.385 inches long and use 7/16-inch ARP 8740 bolts, and forged 4032 Mahle pistons with a -3cc dome and a 4.280-inch bore size. This assembly is ready for serious use, including racing, nitrous, and forced induction setups.

The forged 4340 steel crankshaft is a strong foundation for high-performance builds, offering durability under demanding conditions. The 6.385-inch H-beam connecting rods are well-known for their strength and reliability in racing environments, and the inclusion of ARP 8740 bolts ensures a secure connection. The Mahle pistons are forged from 4032 aluminum, a material chosen for its good thermal expansion properties, and feature a -3cc dome to help achieve a specific compression ratio when paired with the right cylinder heads. This assembly also comes with plasma-moly file-fit piston rings, which allow for precise gap setting to match your engine's bore and intended use, and King XP rod and main bearings, known for their robust performance.

This Eagle rotating assembly is balanced as a complete unit, saving you a significant step in the engine building process. It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. For optimal results, ensure you consult with your engine builder or refer to detailed specifications for proper installation and component matching, such as cylinder head volume and camshaft selection, to achieve your desired performance goals.
