This Eagle Street & Strip rotating assembly gives you the core components to rebuild or upgrade your Ford FE engine. Inside this kit, you'll find a 4.250-inch cast crankshaft, a set of 6.700-inch I-beam connecting rods equipped with 7/16-inch ARP 8740 bolts, and 4.170-inch forged 4032 Diamond pistons featuring a -21cc inverted dome design. It also comes complete with plasma-moly file-fit rings and King rod and main bearings, so you have the essential pieces to get your engine turning again.

This assembly is built for street applications running on pump gas and is designed for naturally aspirated setups. The forged 4032 pistons are a solid choice for street performance, offering good durability and heat resistance. The inclusion of ARP 8740 bolts for the connecting rods means you're getting strong, reliable fasteners that are a step up from stock. The plasma-moly file-fit rings allow for precise gap setting, which is important for optimal sealing and performance in your FE engine.

When putting this assembly together, pay close attention to the piston ring gap, as these are file-fit rings. Proper gapping is crucial for engine health and performance. This rotating assembly is intended for street use and is not CARB approved, meaning it cannot be shipped to California. Always refer to the manufacturer's detailed installation instructions for specific torque values and procedures to ensure a successful build.
