I have a Griffin now, but the original unit that EM spec'd in the car was one from a 1967 Skylark w/ a big block (403??). I had no trouble but wanted a little bit more heat transfer, so went aluminum. If you are going to try the older style radiator, I would ask the radiator company for the dimensions and make sure that it will fit FIRST, as the frames have changed over the years. If you don't have the radiator mounting hardware, post here and I will measure mine and get you some dimensions so you can make one. It is pretty basic, so you should not have too much trouble.
