About this part

Product Details

Eagle has built a solid reputation for making strong engine components, and this balanced rotating assembly is a prime example of their work for Chevy 454 engines. If you're building a street-driven vehicle that runs on pump gas and doesn't use a supercharger or turbo, this assembly is designed to handle that kind of setup. It's a complete package that takes the guesswork out of matching critical rotating parts.

Inside this assembly, you'll find a 4.250-inch cast crankshaft, which is a robust piece for this application. It's paired with 6.385-inch I-beam connecting rods that come equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability. For the pistons, Eagle has included forged 4032 Icon pistons with a 23cc dome, sized at 4.280 inches. These pistons are fitted with plasma-moly file-fit rings, allowing for a precise fit during installation. To top it off, the assembly includes King SI rod and main bearings, ensuring smooth operation and proper clearances for the crankshaft and connecting rods.

This assembly comes balanced from the factory, which is a crucial step in ensuring your engine runs smoothly and lasts longer. Balancing reduces vibration and stress on other engine components. Keep in mind that this part is not CARB approved and cannot be shipped to California. It's a well-thought-out rotating assembly ready for your next street performance build.
