I am the OP for this thread. I got a Cold Case Radiator for my most recent build because they were proactive enough to pm me when I started this thread and make an argument for the quality of their products and their willingness to stand behind them. Since I was building a car for long distance trips, I was really concerned about having problems in the middle of nowhere. I put 6000 miles driving the car across country last year and had not a bit of issue with cooling even though it was 2 lane blacktop across CA, AZ, NM, TX and OK on Rt 66 in the middle of summer.
The same guy that responded here recently was my contact and as he mentioned he made me an excellent deal on the Radiator. I did have to fab some simple brackets for the four bolts for the fan shroud, but not a really big deal.
