I am in the middle of my 32 build. I spent more than 40 hrs over 2 months researching radiators for street rods. Names such as Be Cool, PRC, Walker, AFCO, US Radiator, Griffin and customs like Ron Davis, McCullogh.

Whether you go brass/copper or Aluminum I have concluded boils down to personal preference. As an engineer I can tell you that it is easy to spin technical pro or con in either direction; in the end they are both successful materials for radiators with many many successful applications in each case.

To me the size/capacity of the 32 radiator makes the use of internal cooling tanks undesireable. I live in Texas so cold ain't much of an issue. But then there are also thermostat control external trans cooler circuits available.

I bought an AFCO 32 Roadster Aluminum all welded rad and I am quite pleased with the quality. It also fits my bobbed/pinched front end with its standard lower tank. I am a tad leary of epoxied tanks/tubes. I have gotten advice in here that the upper rod support bracket may need to be reinforced.

Good Luck! Kitz
