Casting flaw ?

elwood, Is there any chance you saved any bearing inserts from this engine?
If so, look at the backs. If original, there will a Ford logo or similar. If replacement inserts, there will most likely be a date code and brand insignia stamped on the back (along with any undersize). If original inserts, you will know that this crank lived a long and happy life, and will be good for more.
If replacements, the date code will give a good idea of how that crank lived after overhaul.
