Eagle is well-known for making strong internal engine components for performance applications. This competition rotating assembly is built for serious use, whether you're building a race engine or a high-performance street machine that needs to handle extra stress from things like nitrous or forced induction.

This assembly starts with a 3.750-inch forged 4340 steel crankshaft, which is a solid foundation for a powerful engine. It's paired with 5.700-inch H-beam connecting rods, known for their strength and reliability under load. These rods use 7/16-inch ARP 8740 bolts to ensure they stay securely fastened. The pistons are forged 4032 aluminum from ICON, measuring 4.155 inches in diameter and featuring a -23cc inverted dome design. They come with plasma-moly file-fit rings, giving you the flexibility to set your ring gaps precisely for your application. To top it off, the assembly includes King XP rod and main bearings, which are designed for demanding use and offer improved durability.

This rotating assembly is designed for Chevy 400 blocks using 350 mains. Keep in mind that this part is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
