Thanks, that makes a lot more sense since everyone I've talked to seems to have a different opinion on torque specs and I went on the most common ones I heard. Just trying to get it as
close to "right" as I can so I don't have any more problems with it in the near future.

You are correct, it just ruined the babbit, it didn't actually spin the shells. #3 and #4 were the worst and almost completely destroyed. #1 was fine except for a tiny grove down the
middle on both halfs and a little material build up. #2 just had a rough bearing surface. I replaced all 4 sets so I know they are all good now.

That's the one things the previous owner suggested, and it makes the most sense since #3 and #4 are farthest from where the oil bar feed comes in. Is there a easy way to take it out to
clean it or clean it in place? I was thinking blow air through each hole while plugging the rest to make sure they are all clear, though I don't want to cut any corners on this so if there
is a better way to clean it I'd be open to suggestions. I know I will be towing it and making sure everything is getting oil before trying to start it to be safe.

I did manage to get all the holes to line up for the pins by switching around the nuts and all the torques are around 50-60lbs. The head is now back on and will be torqued at 90lbs. I have
2 of the 4 pinned in and doing a final check and finishing the other 2 later today.

The only other question I have is I am slightly worried about the #4 rod, as it was the worst one to spin and needed a bit of work on the crank. All the others (#1-3) I can wiggle back and
forth very easily. #4 however, it still turns easily on the crank and I can't feel it dragging any as the engine turns smoothly and easily, but I can't wiggle it back and forth (front to
back) like the rest. Is this going to be a problem? I did get it to wiggle after turning the crank over for a few minutes, though then I took the cap off to do a final check before putting
the pins in and now it won't wiggle again. Not sure if it just needs to break in or if it's too tight or something so any advice on that is appreciated.

Thanks for all the help and advice, it really is greatly appreciated.
