Eagle Ford 8BA Flathead Cast Crankshaft

What you get here is a well-built cast crankshaft from Eagle, specifically designed for Ford 8BA Flathead engines. This is a solid alternative and an upgrade over your original factory crankshaft. It features a 4.250-inch stroke and 2.000-inch rod journals, ready to be the heart of your engine build.

Eagle has improved the strength of this cast crank by incorporating .092-inch fillet radii at the journals. This detail might seem small, but it makes a notable difference in durability. The good news is that even with these stronger radii, you can still use your original equipment (O.E.) replacement bearings, which simplifies sourcing parts for your rebuild. This crankshaft is recommended for use in everyday road cars running on pump gas, especially those that are naturally aspirated and not intended for competition use. It’s built for reliable performance in a street-driven vehicle.

If you're rebuilding the bottom end of your Ford Flathead, this Eagle cast crankshaft offers a strong foundation. It’s a popular choice for those looking for a dependable, upgraded component that maintains compatibility with common bearing sizes. Just remember to check the manufacturer's installation instructions for any specific requirements during your build.
