Also both the upper and lower number 2 rod bearing are pretty well beat. They'll need replaced, and hope that the crank and rod don't eat it again. I'll blow compressed air through the oil hole and make sure it's not plugged, but i think this is damage that was over the long term and finally reared it's ugly head. Luckily the other 2 bearings i've seen so far have looked great. I can re-assemble the other rod bearing, but i'll have to figure out what to do about that shimmed main.

Edit: I found the FM was federal mogul, and the 1535.sb is the part number for a rod bearing for this motor, or was, i don't see it on their site or cross reference any more.

I'm assuming the STO or 030 or whatever it is is the size, i'll plastigauge and reinstall this rod and check another that's easy to get to.

Ross, do you have some spare used rod bearings of different sizes? If you do, i'll gladly buy them and put them in one at a time with pastigauge to see which one is closest. Of course, first i'll mic the rod and post back here.
