Thanks for the info guys. The first time I had a problem was with the #3 main spinning , The register was screwed up and the bearing did spin and the crank was junk. However after looking at all the parts the outcome of the problem was that I had some stretched main studs. Now after all was put back together with all new parts and machine work(Yes align bored,tightened up on the registers,new arp studs and lunati crank balanced to match my bob weights) and after about 20 runs, I took the motor apart for winter check up. The registers are in good shape the crank in like new shape, journals perfect, and just some slight wear on the lower main bearing half. Like I said earlier, I think I might have too much timing from the minor scuffing on the lower main bearing halves. The motor has run very strong with no indications of problems. But the way the bearings look, It has me concerned.Most guys wouldn't think there is anything wrong with the way the bearings look, but I think I may be on the right track.
