About this part

Product Details

This Eagle Street & Strip rotating assembly gives you the core components for a robust Ford FE engine build. Inside this package, you'll find a 3.980-inch cast crankshaft, ready to handle the demands of a street-driven vehicle. Paired with it are 6.490-inch H-beam connecting rods, known for their strength and reliability, secured with 7/16-inch ARP 8740 bolts. These rods connect to a set of 4.185-inch forged 4032 pistons. These pistons feature a -6.2cc flat-top design, which is ideal for pump gas and naturally aspirated applications, helping to achieve a good compression ratio without needing exotic fuel.

To ensure proper sealing and performance, this assembly includes plasma-moly file-fit piston rings. File-fit rings allow for precise gap setting, which is crucial for optimal ring seal and combustion efficiency, especially in modified engines. For the critical bottom end, King rod and main bearings are included. These bearings are well-regarded for their durability and ability to maintain oil pressure under various operating conditions. This rotating assembly is designed for street vehicles running on pump gas and is a solid choice for naturally aspirated builds where reliability and performance are key.

It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always consult the manufacturer's installation guide for specific details regarding assembly and break-in procedures to ensure the longevity and performance of your new engine components.
