Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 18.3cc Dome 4.310in Pistons Balanced Assembly

This is a balanced rotating assembly from Eagle, specifically built for Chevy 454 engines. It's designed for street use with pump gas and naturally aspirated setups, making it a solid choice for rebuilding or upgrading your engine's core components. This assembly includes a 4.000-inch cast crankshaft, 6.135-inch I-beam connecting rods with 7/16-inch ARP 8740 bolts, and forged 4.310-inch Icon pistons with an 18.3cc closed chamber dome. It also comes with plasma-moly file-fit rings and King SI rod and main bearings.

The Icon pistons are forged from 4032 aluminum, known for its good thermal expansion properties, which helps maintain piston-to-wall clearance as the engine heats up. The 18.3cc dome shape is designed to work with specific cylinder head volumes to achieve a desired compression ratio for pump gas operation. The I-beam connecting rods are a strong and popular choice for street performance, and the inclusion of ARP 8740 bolts means you're getting reliable hardware for the rod assembly. Everything in this kit is balanced as a complete assembly, which is crucial for reducing engine vibration and wear, especially at higher RPMs.

When installing this rotating assembly, remember that the plasma-moly rings are file-fit, meaning they need to be gapped to your specific cylinder bore size. This ensures proper sealing and performance. It's also important to follow the manufacturer's lubrication and assembly procedures meticulously, especially when installing the King bearings. This assembly is intended for naturally aspirated applications and is not CARB approved, so it cannot be shipped to California.
