tolass,
I had a 67 that I bracket raced for years. I am not sure what you guys are allowed to do as far as modifications but somewhere along the line I installed a radiator out of around an 85 Camaro. Aluminum radiator with plastic tanks with the attached shroud / electric fan combination. It was very light and worked fine cooling an approx 550 hp small block. I had to do a slight modification to the core support because it was a little wider than the stock radiator but it was nothing major.
