Product Details

This is the Eagle Ford FE Street & Strip Rotating Assembly, designed for naturally aspirated, pump gas applications in your Ford FE engine. It’s a well-built package that gives you the core components needed to rebuild or upgrade your engine's bottom end, focusing on reliable performance for street use.

At the heart of this assembly is a 3.980-inch cast crankshaft, paired with 6.490-inch H-beam connecting rods. These rods are secured with strong 7/16-inch ARP 8740 bolts, a detail that speaks to the serious nature of this build. The pistons are forged 4032 Diamond units, featuring a -6.2cc flat top design and a 4.100-inch bore size, intended to work with your specific cylinder heads. You'll also find plasma-moly file-fit piston rings, which allow for precise gapping to match your engine's needs, and King SI rod and main bearings to ensure smooth rotation and proper oil clearance. This combination is put together to offer a solid foundation for a street-driven performance engine.

When building an engine, especially one like the Ford FE which can be a popular choice for performance builds, having a balanced and well-matched rotating assembly is crucial. This Eagle assembly takes the guesswork out of selecting compatible crank, rod, and piston combinations for a naturally aspirated setup. Keep in mind that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
