Bell Never Aligned

I always install the dial indicator in the crank and dial to the hole in the bellhousing. I have made special tools over the years to set it up and get the alignment. It usually takes about 45 minutes to realign a bell housing on a small block. Because you can punch the dowels out, not like a big block. In answer to another question never have replaced a offset dowel, every one I have done still have the original dowels in them.
