Product Details
Starting with a 4.250-inch stroke cast crankshaft, this balanced rotating assembly from Eagle is built for your Chevy 454 engine. It's designed for street vehicles running on pump gas and naturally aspirated setups, making it a solid choice for many builds. The assembly includes 6.385-inch I-beam connecting rods, which are a common and reliable choice for street performance applications.
The pistons included are Hypereutectic KB flat tops with a -3cc dish, designed to work with a 4.350-inch bore. They come with plasma-moly file-fit rings, giving you the flexibility to achieve a precise fit in your cylinders. For reliable lubrication, the assembly is fitted with King SI rod and main bearings. The connecting rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and dependability in performance applications.
This assembly comes balanced from the factory, which is a critical step in ensuring smooth engine operation and longevity. Balancing reduces vibration and stress on your engine's internal components.
