Well I found it...

#1 Rod bearing spun. Almost completely gone, nothing left but a paper thin shell. The crank bearing surface checks in spec, tomorrow I'll check the rod for ovality. Certainly the damage on the other bearings is as a result of the loss of oil pressure because of the spun bearing.

Now, why did the #1 bearing fail. More than likely because of a couple missed shifts in the last 3.5 seasons and a few 'caught it' money shifts. The bearing just slowly broke down untill the loss of oil pressure caused it to fail completely.... ...however I'd entertain other ideas!
