Did you measure that clearance with a micrometer and bore gauge or did you use plastigauge? Both work but one is more accurate than the other.
Also, I can’t think of a time when bearings were as inconsistent as they are now.
To get my mains where they should be it took two sets of bearings.
Also, did you measure that .002 on that rod and throw? When the clearance is getting under .001/per inch of shaft diameter you need to stay away from any grade of oil with a higher grade than 30.
You just don’t need it.
