I made a call down to South Carolina this morning and had sent a few emails to the nascar engine shops I'm in contact with. They told me the same thing to chamfer the bearings. When I told one of them I was scraping the bearing he laughed and said are you crazy???? Use a dremel with a small metal bit. You'll be scraping forever to get enough clearance. Another said they use their lathes to turn them down. Not sure how that works.

But anyway I got my air dremel tool out and put my small metal bit in I use for porting and lightly went over the bearing edge. It does a much smoother job than scraping and it turned out very well. Almost looks machined.

Thanks Mr. P for all the tech help, it's greatly appreciated

Now when I rotate the assembly all the rods go to the radius instead of the center of the crank. I have .040+ clearance between the rods now.
