I think a very good book for the 351W engine you have is HPBooks How to Rebuild Small-Block Ford Engines Book By Tom Monroe. I have the Steve Christ book for the Big Block Fords and it is simply outstanding.
I agree with Wayne, the culprit has been something which was either inside the
oil pump or the pickup tube ( some loose casting material or a welding residue from a not so good product) , because I can not imagine anything that big getting past the screen.
You HAVE to get the crank out: pěcture 17 shows a main journal I would not like to live with.One of the Con rods has taken some heat (the yellowish one) and is probably deformed, so you will have to replace that one too.
Mentalize yourself that the engine has to come out and the crank reground. You will need some bits and pieces to replace broken parts.
Otherwise nothing that can not be done. Plenty of help here in the Forum too.
