Eagle Chevy 454 4.000in Crank 6.385in H-Beam -3cc Flat Top 4.320in Pistons Rotating Assembly

This Eagle Competition Rotating Assembly is a complete package for your Chevy 454 engine build, designed to handle serious performance demands. What you get in this kit is a forged 4.000-inch stroke crankshaft made from 4340 steel, a set of 6.385-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and forged 4.320-inch flat-top pistons with a -3cc dish. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your engine rotating smoothly and reliably.

Eagle built this assembly with racing in mind, making it a solid choice for applications involving nitrous oxide or forced induction. The 4340 forged steel crank and H-beam rods are known for their strength, able to withstand the higher cylinder pressures and stresses these power adders create. The SRP pistons are forged from 4032 aluminum, which offers good thermal expansion properties for a tighter piston-to-wall clearance, contributing to improved ring seal and reduced noise. The included file-fit rings allow for precise gapping to match your specific engine build and intended use, whether it's for the drag strip or a high-performance street machine.

When putting this assembly into your 454, remember that the file-fit rings will need to be gapped correctly for your application, so consult your engine builder or a trusted manual for the proper clearances. This kit is intended for competition use and is not CARB approved, meaning it cannot be shipped to California. Ensure you check all local emissions regulations before purchasing.
