Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods Closed Chamber 4.310in Pistons Rotating Assembly

Eagle has a solid reputation for making well-built performance engine parts, and this Pro Street rotating assembly is a prime example for your Chevy 454. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of use. It includes everything you need to get your bottom end built right, with components chosen for strength and reliability under pressure.

At the heart of this assembly is a 4.000-inch forged 4340 steel crankshaft, providing a strong foundation for your build. Paired with it are 6.135-inch I-beam connecting rods, also made from durable 4340 steel and secured with 7/16-inch ARP 8740 bolts. These rods are built to withstand the forces generated in a high-performance engine. The pistons are forged 4032 aluminum from ICON, featuring a 4.310-inch bore size and a 18.3cc closed chamber dome design, which is ideal for achieving specific compression ratios in naturally-aspirated applications. The assembly comes complete with plasma-moly file-fit rings and King XP rod and main bearings, ensuring proper clearances and lubrication right out of the box.

This rotating assembly is a significant step up for anyone looking to build a serious racing engine. Keep in mind that this part is not CARB approved and 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.
