Eagle Chevy 454 4.000in Crank 6.135in H-Beam -3cc Flat Top 4.350in Pistons Balanced Assembly

If you're rebuilding a high-performance Chevy 454 engine, especially for racing applications, a balanced rotating assembly like this one from Eagle is a solid foundation. This assembly includes all the core components you need to get your engine's bottom end ready for serious power, whether you're running nitrous or forced induction.

Eagle starts with a forged 4340 steel crankshaft featuring a 4.000-inch stroke. Paired with this are 6.135-inch H-beam connecting rods, known for their strength and reliability under stress. These rods are secured with 7/16-inch ARP 8740 bolts, a name you can trust for high-performance engine builds. The pistons are forged 4032 aluminum from Icon, designed with a -3cc flat top dish to work with a 4.350-inch bore and a 4.000-inch stroke, and they come with plasma-moly file-fit rings, allowing for precise gap setting to match your engine's needs. To top it off, King XP rod and main bearings are included, offering excellent durability and performance for the critical rotating components.

This assembly comes balanced from Eagle, which is a crucial step for any performance engine build. Balancing reduces vibration and stress on your engine's internal components, leading to a smoother running engine and potentially longer life. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and torque specifications.
