Radiator and cooling options

Frnknsteen, can’t offer anything that hasn’t already been said, but I have a question.
Do you recall where you got those upper radiator brackets, or does anybody else following this know where to find brackets like that?
Edit: I had only gone through about 1/2 the thread when I asked. Glad you got it sorted out. I will add that I would do some more tests next summer. Now that you have everything working correctly, and enough capacity, you may want to start upping your operating temperature. I don’t know the “ideal” temp, but 200 or a bit over is supposed to be more efficient, & cleaner. You might even check your oil temp. You want it hot enough to drive off moisture created by the combustion process. (If you aren’t already burned out on tracking temperatures)
