Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 18cc Dome 4.280in Pistons Rotating Assembly

Eagle has a solid reputation for making well-built performance engine components, and this Street & Strip rotating assembly for the Chevy 454 is a prime example. If you're rebuilding the heart of your naturally aspirated, pump-gas street vehicle, this assembly is designed to handle the demands of regular driving while offering improved performance over stock.

This kit centers around a 4.000-inch cast crankshaft, paired with 6.135-inch I-beam connecting rods. These rods are equipped with 7/16-inch ARP 8740 bolts, a strong choice for ensuring reliable connection under load. The pistons are forged 2618 material from ICON, featuring an 18cc closed chamber dome design and a 4.280-inch bore size, which is crucial for achieving the correct compression ratio for pump gas applications. You'll also find plasma-moly file-fit piston rings, allowing for precise gap setting during installation, and KING SI rod and main bearings to ensure smooth rotation and proper oil clearance. This combination is built for durability and performance on the street.

When assembling this rotating unit, pay close attention to setting the correct piston ring end gaps using the file-fit rings, as this is critical for proper sealing and performance. This assembly is intended for naturally aspirated, pump gas street applications and is not CARB approved, meaning it cannot be shipped to California. Ensure you have all necessary supporting components for your engine build, such as gaskets, seals, and a balanced rotating assembly, before installation.
