I'll add that I also have a '96 Corvette that I put an aluminum BeCool radiator in. The stock radiator was a aluminum one with plastic tanks. The stock radiator started leaking at the seal of the plastic tank with the aluminum core.
I took the stock one out and had it recrimped which was good for almost two years before it started leaking again. :-( I found a BeCool off of ebay and won and installed it in the 'Vette instead of using another plastic tank aluminum stock one.
The temps in the 'Vette are usually around 190 degrees with the BeCool(188 in the winter). With the stock radiator, my temps were usually around 194 degrees both using the same stock 185 degree thermostat.
The BeCool does cool much faster than the stock radiator and does not reach as high a temperature as fast as the stock radiator either as well as keeps the oil temperature cooler.
It is a very nice radiator.
My Mustang was my first car and I really haven't driven it as much as I should as it was sitting at my parents house a few hours away. I decided I wanted to bring the Mustang down except it liked to overheat whenever it was on the highway for any period of time(like a half-hour).
I decided I'd buy a new radiator for it. I looked at the aluminum ones, but the $400-$500+ price tags didn't really appeal to me. I then saw that 4 core copper/brass 24" 390/428 radiator for $230 and thought that if that doesn't cool my car, then something has to be wrong with my car.
As it turned out, my old 2 core 24" radiator was clogged up more than I thought and that is probably the reason why I was overheating.
Anyway, the point that I'm trying to make is that I've had both aluminum and copper/brass radiators and they both can cool well. Yeah the aluminum radiators look cool and are lighter, but I don't regret getting the copper/brass 4 row unit for my Stang.
If you can get a good deal on an aluminum unit(and if it's contructed well. Do those Northern "Race-pro" radiators have fins as thick as an aluminum "street" radiator? What's the difference between them?) without much modification, then I would probably get the aluminum one.
I wouldn't pay $500 for an aluminum radiator if all you need is a $165 copper/brass unit though, but then I'm not the one spending the money!
