Eagle Chevy 454 1Pc 4.250in Crank 6.385in I-Beam Rod -3cc Flat Top 4.250in Pistons Rotating Assembly

Eagle is well-known for making strong engine components, and this Street & Strip Rotating Assembly is a prime example for your Chevy 454. If you're building a street-driven vehicle that runs on pump gas and doesn't use a supercharger or turbo, this assembly is designed to handle that kind of use. It's a complete package to get your engine's bottom end rebuilt with reliable parts.

This assembly starts with 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 a solid choice for ensuring everything stays tight under load. The pistons are hypereutectic KB flat tops with a -3cc dish, designed to work with a 4.250-inch bore. They come with plasma-moly file-fit rings, giving you the flexibility to set the ring gap precisely for your build. To round it out, the assembly includes King rod and main bearings, known for their durability in street applications.

When putting this assembly together, remember that the plasma-moly rings are file-fit, meaning you'll need to gap them yourself to match your specific engine build and intended use. This is a common practice for performance builds to ensure proper sealing and longevity. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
