Thanks for the input. I commented originally it was as much as Art as Science to get one of these things to run at temperature now I think I have to add Magic! Seriously, I know there is science at work here but it sure seems you have to chase this issue for most cars until you get it resolved. Brian, I'm glad your engine is not overheating. I will seal the radiator well and look at fabricating a shround unless one of you B&B guys know what shroud/fan combo works with the room allowed and where I can buy one. (Brian, is yours the standard brass radiator B&B provides?)
I noticed David Kirkham said they do not shround their radiators so air will flow through them at speed and not be hampered by a fan or shroud that might slow airflow. They do seal them off however.
Thanks for the thoughts and I would welcome any other advice.
