I agree that aluminum dissipates heat better, however I've been daily
driving my '57 GMC in Houston's summer traffic with the A/C running and
have had no problems with overheating since I had a local radiator shop
put a new core in mine in 1995. The old one was half stopped up and
sprung small leaks once or twice a year. I had them remove the top and
bottom tanks, throw away the old core and replace it with new. I run an
overflow recovery tank, a good fan shroud and a 7 PSI (stock) radiator
cap. A 160 degree thermostat keeps the temp gauge below 175 in all but
the most extreme conditions and I've never seen it over 190. Engine is
the Pontiac 347" V8 that came in my truck.
