Fully groves mains

So, I think if you have a raised edge from the cut, it may have the propensity to squish both in and outside of the groove. This could be a problem when the mains are torqued. The babbit can accumulate and get dragged around by where the oil hole is. I had an LS motor in a yukon that was seized, when I took it apart, there had to have been a 1/8 groove in the bearing, and a chunk that had grown considerably, ultimately stopping the crank from rotating. I still have the bearing, can probably find a picture. But anyway, to mitigate this problem, you can always make a bearing scraper out of an old file. Grind down and sharpen the 3 sides of the file about an inch, and scrape the burrs. I usually use this on new cam installs. Put it in, turn it, see where it’s tight(marks on bearing) and scrape each part until it moves freely. You could probably use a knife. I was advised to not try and use scotch bright pads on bearing material to remove burrs
