About this part

Product Details

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

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 applications. For the pistons, you get Hypereutectic KB flat-top pistons with a -3cc dish, designed for a 4.310-inch bore. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your specific cylinder bore and ensure good sealing. King SI rod and main bearings are also included, providing solid lubrication surfaces for the crankshaft and connecting rods.

This assembly comes balanced from the factory, saving you a significant step and cost in your engine build. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure the longevity of your new engine components.
