The Eagle cast crankshaft for Ford 8BA flathead engines is supplied as a stronger alternative to OE units, featuring .092" fillet radiuses for increased strength while retaining compatibility with standard replacement bearings. It’s intended for pump‑gas, naturally aspirated, non‑competition road cars where durability is desired without custom bearing changes. The crank is cast and specified for a 4.250" stroke.
