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

What you get here is a complete, balanced rotating assembly for your Chevy 454 engine, ready to be installed. This package includes a forged 4340 crankshaft with a 4.250-inch stroke, a set of 6.385-inch H-beam connecting rods fitted with 7/16-inch ARP 8740 bolts, and forged 4032 Icon pistons. These pistons are a 23cc dome design and measure 4.250 inches in bore size, paired with plasma-moly file-fit rings. To top it off, this assembly comes with King XP rod and main bearings, all balanced as a complete unit for smoother operation.

This assembly is built for serious performance, especially if you're planning on using nitrous or forced induction like turbochargers or superchargers. The forged 4340 crank and H-beam rods are strong enough to handle the extra stress these power adders can create. The Icon pistons are also forged, offering a durable and lightweight option for high-performance builds. The inclusion of ARP bolts means you're getting reliable hardware for the connecting rods, and the King XP bearings are known for their robust performance under demanding conditions. Having the entire assembly balanced from the start saves you a significant step and ensures your engine's internals are properly matched for reduced vibration and improved longevity.

Keep in mind that this assembly is not CARB approved, so it cannot be shipped to California. It's designed for racing applications where maximum performance is the goal. Make sure you have the correct machine work done on your block to accept these components, and always follow the manufacturer's installation instructions for proper assembly and break-in procedures.
