got the engine in and it runs like a top, a very stout top at that...seems I have 2 bad temp sending switches to turn on and off my electric fans for cooling...the engine with get to 210 and no fans...they are set at 185 and 195...checked all the wiring and everything seems fine but no fans...I connected the positive terminal of the unit to the shell and the fans came right on...the come on when hot wired so I am assuming the only weak link is non functioning switches...done for the day, time to relax my mind and watch a little nascar...
