About this part

Product Details

If you're building a Ford FE engine for street use with pump gas and no power adders, this Eagle Street & Strip rotating assembly is a solid foundation. It's designed to handle the demands of a naturally aspirated setup, giving you the core components needed to get your engine internals sorted.

This assembly starts with a 4.250-inch cast crankshaft, paired with 6.700-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. The pistons are forged 4032 aluminum from Diamond, featuring a -21cc inverted dome design and a 4.160-inch bore size, which helps achieve a specific compression ratio suitable for pump gas. They come complete with plasma-moly file-fit rings, meaning you can gap them precisely for your build. To top it off, the assembly includes King rod and main bearings, offering good performance for street applications.

This rotating assembly is a comprehensive package for your Ford FE engine build. Please note that this assembly is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or refer to manufacturer instructions for specific installation details and compatibility with other engine components.
