Eagle has built a solid reputation for making strong engine components that hold up to the demands of performance driving. This balanced rotating assembly is a prime example, designed specifically for Chevy 454 engines. It's a great choice if you're building a street-driven vehicle that you plan to run on pump gas and keep naturally aspirated, aiming for improved performance without going forced induction.

What you get here is a complete, balanced rotating assembly, meaning Eagle has taken care of the critical balancing work for you. It features a 4.250-inch cast crankshaft, paired with 6.385-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, which are well-known for their strength and reliability in performance applications. The pistons are hypereutectic KB flat tops with a -3cc dish, designed to work with a 4.250-inch bore. This assembly also includes plasma-moly file-fit piston rings, giving you the flexibility to achieve a precise fit in your cylinders for better sealing and performance. To top it off, it comes with King rod and main bearings, which are respected for their durability and consistent performance.
