New owner looking for guidance, here is my cars setup

[captndave737]

I do not want to be "picky", but brass/copper will transfer heat better than copper.

But in the case of radiators, the tubes can be made larger because aluminum is more rigid than copper, and individual tube will flow more.

Years ago we did some field testing on alum vs. copper radiators, and the difference was minimal.
Actually heat transfers better in aluminum than brass and copper conducts heat the best.

The price of high-effiency copper cores has risen out of sight, and the Alradco alum radiators have been designed specifically for GN's,nd now it is certainly the better choice.

Nick,
Here are the heat transfer coefficients. I agree with getting an Alradco. I had boxed my radiator, got a 4 row brass, dual fans etc. and my temps always hovered around 200 and sometimes higher sitting in traffic in the summer in NC. Since the Alradco nothing over 175 and my fans don't even come on until 170 with my extender chip. I've always used 50/50 mix but I'm reconsidering after reading your reasons why not using it.

Copper – 401
Aluminum – 273
Brass – 109 (not 159)

I should have said that better nick. Thanks for catching it. I was referring to the 25 yr old original brass radiators in the gbody cars.
