This problem is common on Mopar BB Two choices that I know of to take care of the bearing and cam fitment issue, one is to have the cam tunnel honed to the proper size and the other, which is what I do now, is to buy a bearing scraper and scrape the tight bearings (a little at a time, don't take big cuts ) until the cam turns easily IHTHs As already said, try the new bearings on each location on the cam before installing them and then install one cam bearing at a time and check the cam fitment, fix the bad ones first and then go to the next one To bad Ma Mopar screwed the pooch on this issue
