Thanks to ALL that helped! Looks like I have a solution. A guy that worked at Delta with me is an unbelievable welder, fabricator. I ran it by him and he came up with a solution. He took the original heater fitting that I got from Napa (screwed into water pump) that was way to small for hose and welded a piece on it. Only issue I had to remove the radiator surround because I did not have a 7/8" stubby to tighten it.
When I take something to him he likes to think about it a while. Same guy fixed the radio cutout in my dash and also cut out in doors for speakers.
The shop that built the engine is sending lead mechanic down (3 hour drive one way) on Wednesday. This beast is going to be fired up for the first time in well over 20 years. I have tried to anticipate everything needed but sure seems like it is good to go. I sure hope so...
