Eagle Chevy 454 4.250in Crank 6.385in I-Beam Rods 18cc Dome 4.280in Pistons Rotating Assembly

This Eagle Street & Strip rotating assembly is built around a 4.250-inch cast crankshaft, forming the backbone for your Chevy 454 engine build. It’s designed for street vehicles running on pump gas and naturally aspirated setups, offering a solid foundation for performance without needing exotic fuel. The assembly includes 6.385-inch I-beam connecting rods, which are a well-built choice for this application, secured with 7/16-inch ARP 8740 bolts for reliable clamping force under load.

The pistons are forged 4032 aluminum from Mahle, featuring an 18cc dome volume and a 4.280-inch bore size. This dome shape is key for achieving a desired compression ratio when paired with specific cylinder heads. The assembly comes complete with plasma-moly file-fit piston rings, allowing for precise gap setting to match your engine's bore and intended use, which is crucial for sealing and oil control. King rod and main bearings are also included, providing a well-matched set for smooth rotation and proper oil clearance.

This rotating assembly is a comprehensive package for rebuilding or upgrading your Chevy 454. While it's designed for street performance, please note that it is not CARB approved and cannot be shipped to California. Ensure you consult with your engine builder or refer to manufacturer specifications for proper installation and compatibility with other engine components.
