Eagle Chevy 454 4.250in Crank 6.385in H-Beam 23cc Dome 4.280in Pistons Balanced Assembly

Eagle is well-known for building strong rotating assemblies that can handle serious power, and this balanced assembly for the Chevy 454 is no exception. If you're building a high-performance engine for racing, especially with nitrous or forced induction, this is a solid foundation to consider. It’s a complete package designed to handle the demands of competition.

This assembly starts with a forged 4340 steel crankshaft featuring a 4.250-inch stroke, providing a good displacement increase for your 454. Connecting the crank to the pistons are 6.385-inch H-beam connecting rods, a popular choice for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, known for their consistent clamping force. The pistons are forged 4032 aluminum from Icon, with a 4.280-inch bore and a 23cc dome dish, designed to work with specific compression ratios. They come complete with plasma-moly file-fit rings, which allow for precise gapping to match your engine's needs. Topping it off, the assembly includes King XP rod and main bearings, offering excellent wear resistance and performance.

This rotating assembly comes balanced from Eagle, saving you a significant step and ensuring your engine runs smoothly and reliably. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's important to consult your engine builder or refer to manufacturer specifications for any additional components or clearances needed for your specific build.
