Is there anything specific I should be looking for that would point out the chain of events that caused the failure? There's no sludge, I have a bad transmission bearing, a bad rod bearing, and a scarred oil pump. What failed first and how can I tell?
I really don't want to do this again

Also, after researching honing / deglazing, I'm heavily leaning towards the green scotch brite method. Only thing I'm worried about is there a little bit of scratches on the cylinder from the piston skirt.

A bottle hone will also de-glaze, scotchbrite, or you can use a hone. I did last time, just limited it to slow turning and counted 8 turns total thru the bore. The coating is very thin and all you want is enough cross hatch to break in the new rings.

actually at aprox 30hp to every 250cc.. that 5liter mustang would be pushing 600 normally aspirated hp!!
that's done with no blower, no turbo, no NOS....that's pretty impressive.
It's truly amazing they stay together as well as they do.

Before I put the crankcases back together, I found that there is an extra ball floating around. Not sure where it belongs.
I've found balls on the following parts:
*Oil pump (x2)
*Rocker assembly (2 on intake, 2 on exhaust)
Any ideas where its from? None of the old bearings were missing any balls.

Should have everything back together tonight.
Any tips for breaking it in? I was thinking of filling up the oil, kicking through a couple times, then draining the oil to get any extra pieces of dirt/metal out. Is that excessive?
