Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods 23cc Dome 4.350in Pistons Balanced Assembly

Eagle has a solid reputation for making well-built engine components, and this balanced rotating assembly is a great example of their work for Chevy 454 engines. If you're building a street-driven vehicle that runs on pump gas and isn't force-fed air, this assembly is designed to handle that kind of use. It’s a complete package that takes the guesswork out of matching critical rotating parts.

This assembly starts with a 4.250-inch cast crankshaft, paired with 6.385-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, which are known for their strength and reliability, especially under the stress of regular driving. For the pistons, you get forged 4032 aluminum pistons from ICON, featuring a 23cc dome and a 4.350-inch bore size. These pistons come with plasma-moly file-fit rings, meaning you can adjust them for a precise fit during installation, which is important for good sealing and performance. The whole assembly is balanced at the factory, saving you a significant step and ensuring smooth operation right out of the box. It also includes King SI rod and main bearings to get your build started.

Keep in mind that this assembly is not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine components.
