Eagle Chevy 454 4.250in Crank 6.385in H-Beam 23cc Dome 4.320in Pistons Rotating Assembly

This Eagle Chevy 454 competition rotating assembly is a well-built package designed for serious performance applications. It's a complete rotating assembly, meaning it includes the crankshaft, connecting rods, pistons, piston rings, and bearings all balanced and ready to be installed into your Chevy 489 big block engine. This assembly is specifically put together for demanding use, including racing scenarios that might involve nitrous oxide or forced induction like turbochargers or superchargers.

At the heart of this assembly is a 4.250-inch forged 4340 steel crankshaft, chosen for its strength and durability under high stress. Paired with it are 6.385-inch H-beam connecting rods, also forged from strong 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These ARP bolts are well-known for their reliability and ability to maintain clamping force under extreme conditions. The pistons are forged 4032 aluminum from ICON, featuring a 23cc dome volume and a 4.320-inch bore size, designed to work with the crankshaft and rods for a specific compression ratio. The assembly also comes with plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's bore and intended use, and King XP series rod and main bearings, offering improved performance and durability.

This rotating assembly is a significant upgrade for anyone rebuilding or building a high-performance Chevy big block. It's important to note that this part is not CARB approved and cannot be shipped to California due to emissions regulations.
