Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 38cc Dome 4.250in Pistons Rotating Assembly

This Eagle Street & Strip Rotating Assembly gives you the core components to rebuild or upgrade your Chevy 454 engine for street use. You get a 4.000-inch cast crankshaft, a set of 6.135-inch I-beam connecting rods, and 4.250-inch forged pistons with a 38cc dome. It also includes plasma-moly file-fit piston rings and King rod and main bearings to get your build started right. This assembly is designed for pump gas, naturally aspirated street vehicles.

The cast crankshaft is a solid choice for street applications, offering good durability for everyday driving. The I-beam connecting rods are well-built and come equipped with 7/16-inch ARP 8740 bolts, which are a strong upgrade over stock fasteners, ensuring reliable clamping force under load. The Icon forged pistons are made from 2618 aluminum, known for its strength and ability to handle heat, and feature a 38cc dome that will influence your compression ratio depending on your cylinder head volume. The included plasma-moly file-fit rings allow for precise gapping to match your cylinder bore and desired clearances, which is important for proper sealing and oil control. King bearings are a popular choice for their consistent performance and material quality.

When installing this rotating assembly, pay close attention to the piston ring gap. File-fitting the rings is a critical step for optimal engine performance and longevity, especially in a naturally aspirated build. Ensure all components are clean and properly lubricated during assembly. This kit is intended for naturally aspirated street applications and is not CARB approved, meaning it cannot be shipped to California.
