Only the rod bearings show signs of excessive wear, the main bearings and thrust bearing are fine. What would cause this?

Re: Odd Bearing Wear
Low oil pressure. The rod bearings take the most punishment and are the most sensitive to low oil pressure.

Re: Odd Bearing Wear
It's hard to define "excessive" wear by that photo, if you are assuming they are excessively worn because they are all copper that isn't the case (probably), MANY! AMC sixes are equipt with full copper rod bearings, seen them brand new right out of the box that way!
