Eagle Chevy 454 1Pc 4.250in Crank 6.385in I-Beam Rods 18cc Dome 4.320in Pistons Rotating Assembly

If you're rebuilding the heart of your Chevy 454 for street use, this Eagle Street & Strip rotating assembly is a solid choice. It's designed to handle pump gas in naturally aspirated applications, making it a great option for bringing your engine back to life or giving it a significant upgrade for daily driving and weekend cruising.

This assembly starts with a 4.250-inch cast crankshaft, paired with 6.385-inch I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability in performance builds. The pistons are forged 4032 aluminum from Mahle, featuring an 18cc dome and a 4.320-inch bore size, which are key dimensions for achieving your desired compression ratio. The assembly also includes plasma-moly file-fit piston rings, allowing you to precisely set the ring gap for optimal performance and sealing. To complete the package, King SI rod and main bearings are included, offering dependable lubrication and wear resistance for the crankshaft and connecting rods.

When putting this assembly into your engine, remember that the piston rings are file-fit, meaning you'll need to gap them to your specific application. This is a standard procedure for performance engines and allows for better control over blow-by and oil consumption. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on assembly and installation procedures.
