That may be it as well. It seems that back in the day guys could run their engines without oil at all to try and kill them and they would hold up just on the film that was present. But modern oils are sucking severely these days. It may just be the oil. I lost the thrust running Castrol, which apperantly is some of the worst these days, and this rod bearing just went using Valvoline VR1. I've run Mobil 1 in the past and never had a problem with it, it actually ran in the engine that had the half siezed wrist pin and seemed to keep it from totally galling.

RE: Dammit, not again
I wanted to go 347 last year when I first rebuilt it, but the previous builder had shoved that #1 piston in and it scored the lower portion of the cylinder. It was already .040 over, and going to a 347 would have likely put the top compression ring in a position where it would be passing over the grooves in the cylinder wall. With a 302 it was fine. I was trying to keep cost down by going to another block, but in the end this has proven to be just as costly, if not more so.
