About this part

Product Details

If you're building a Ford FE engine for street use, especially one that will run on pump gas and doesn't use a supercharger or turbo, this Eagle Street & Strip rotating assembly is a solid choice to get your build started. It's designed to handle the demands of a naturally aspirated setup, giving you a strong foundation for your project.

This assembly features a 3.980-inch cast crankshaft, paired with 6.490-inch H-beam connecting rods. These rods use 7/16-inch ARP 8740 bolts, which are well-known for their strength and reliability in performance applications. The pistons are forged 4032 aluminum with a -6.2cc flat top design and a 4.175-inch bore, making them suitable for a wide range of FE engine builds. You'll also get plasma-moly file-fit piston rings, which allow for precise gap setting to match your specific engine build and improve sealing. To complete the package, King SI rod and main bearings are included, offering good performance for street applications.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's important to check all manufacturer installation instructions before beginning your build, as proper assembly and balancing are critical for engine longevity.
