Eagle has a solid reputation for making well-built performance engine components, and this balanced rotating assembly is a prime example for your Chevy 454.

This assembly starts with a 4.000-inch cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under stress. The pistons are KB hypers, featuring a 12cc dome shape and a 4.350-inch bore, designed to work with the rest of the assembly for improved performance.

This balanced assembly means the crankshaft, connecting rods, and pistons have been precisely weighted and matched to reduce engine vibration and improve overall smoothness and longevity. While this assembly is not CARB approved and cannot be shipped to California, it offers a robust foundation for your street-focused Chevy 454 project.
