Eagle Chevy 454 1Pc 4.000in Crank 6.135in I-Beam Rods 18.3cc 4.310in Pistons Balanced Assembly

When you're building a Chevy 454 engine for street use, especially one that will run on pump gas and be naturally aspirated, getting the rotating assembly right is key. This balanced assembly from Eagle includes a 4.000-inch cast crankshaft, 6.135-inch I-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and 4.310-inch forged ICON pistons. The pistons feature an 18.3cc closed chamber dome design, and the assembly comes with plasma-moly file-fit rings and King rod and main bearings.

This assembly is balanced from the factory, which saves you a significant step and cost during your engine build. The ICON pistons are forged from 4032 aluminum, known for its good thermal expansion properties, making them well-suited for street applications. The inclusion of ARP bolts for the connecting rods means you're getting strong, reliable fasteners that are a step up from standard hardware. The plasma-moly file-fit rings allow for precise gapping to match your specific engine build and bore size, ensuring a good seal.

This balanced rotating assembly is intended for street performance builds and is not CARB approved, meaning it cannot be shipped to California. It's a well-built foundation for a powerful and reliable naturally aspirated 454 engine.
