Eagle Chevy 454 4.000in Crank 6.135in H-Beam 18cc Closed Chamber 4.250in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, specifically designed for Chevy 454 engines. It's a well-built package intended for serious competition use, whether you're building a dedicated race car or a powerful street/strip machine that sees track time. A rotating assembly is the heart of your engine's bottom end, consisting of the crankshaft, connecting rods, pistons, rings, and bearings. Getting these components balanced and working together is crucial for reliability and performance under demanding conditions.

Eagle has put together a strong combination here. You get a 4.000-inch forged 4340 steel crankshaft, which is known for its durability and ability to handle significant stress. The connecting rods are 6.135-inch H-beam units, paired with 7/16-inch ARP 8740 bolts for a solid connection to the pistons and crankshaft. The pistons are forged 2618 aluminum from ICON, featuring an 18cc closed chamber dome design and a 4.250-inch bore size, ready for a high compression ratio. This assembly also includes plasma-moly file-fit piston rings, allowing you to set the ring gap precisely for your application, and King XP series rod and main bearings for excellent lubrication and wear resistance.

This rotating assembly is a significant upgrade for anyone looking to build a high-horsepower 454. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure you have the necessary machine work done to your block, such as boring and honing to the piston size and balancing the entire assembly, for optimal results and longevity.
