Eagle is a well-known name in performance engine building, and they're known for making strong rotating assemblies that hold up to serious use. This balanced assembly is built for Chevy 454 engines and is designed for all forms of racing, including applications using nitrous or forced induction. It’s a complete package to get your engine’s bottom end rebuilt with reliable parts.

At the heart of this assembly is a forged 4340 crankshaft with a 4.250-inch stroke. Paired with it are 6.385-inch H-beam connecting rods, which are a popular choice for their strength and durability under high loads. These rods use 7/16-inch ARP 8740 bolts to ensure a solid connection. The pistons are forged 4032 Mahle flat tops, featuring a -3cc dish and a 4.350-inch bore size, designed to work with the crank and rods for optimal compression. This assembly also comes with plasma-moly file-fit piston rings, which allow for precise gapping to match your specific engine build. For the main and rod bearings, King XP bearings are included, known for their robust construction and ability to handle demanding conditions.

This assembly comes balanced from the factory, saving you a significant step in the engine building process. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
