Today, I got the engine on the stand and flipped over to inspect the bearings (mains and rods). Found some interesting things...

Three of the four rod caps had castellated nuts, but no cotter pins. Cylinder No. 1's rod caps didn't have castellated nuts, just plain ole machine nuts. No washers, even. frown

The rod caps were all tighter than 35 ft lbs and the mains were at least 70. None the less, per the conversations with Jerry and Dean, once I have my shims together, I will be headed back over to take all the rod caps off and then the mains to recheck everything.

I took the oil pan off my parts engine and robbed it of a couple of castellated rod cap nuts. That engine was missing it's oil pump intake screen ... Among other things ...

Hopefully, I can spend a full day back over there soon and go through it all. With shims ... one at a time ... At least it's only 7 bearings ...
