I dont think the Mustang Club of America puts BS in their monthly magazines

You are simply repeating something you read, while he actually called the company and spoke to someone. Now be honest, who would you believe?

I just called radiators.com and they too told me that they do not have any aluminum radiators. They said they only have copper radiators for my application (68 w/a 302)

well im calling MCA or radiators.com monday to figure this junk out. I dont see MCA putting fake stuff in their magazines.

Calling MCA would be good. I'm still looking for someone with a Griffin radiator. Could you tell me what part number you have?

Personally I think the weight savings and the cool appearance is the main advantage. A copper/brass radiator (like your stocker) actually cools a bit better, but doesn't look nearly as neat. Be prepared to fabricate mounting brackets, since they don't just bolt in, but it's not brain surgery. Also, have the general dimensions (height x width x thickness) of your stocker, plus the outlets location when you order.

This is NOT true. Brass does not cool better. Aluminum is entirely superior, and that's why new cars all have aluminum radiators.

Brass/Copper has better heat transfer but because of its density the transfer is SLOW. Aluminum is less dense than brass/copper, while it doesnt have the same amount of heat transfer it does have quick heat transfer which is what really matters in cars. The quicker you can get the heat into the fins the quicker the air can pass over and remove the heat. So in the car game, quicker heat transfer is better than heat transfer as far as absorption amount.

While 65Fastback2+2 beat me to it (Thank You ) He's 100% right. New cars have used them for years for the same reason motocross bikes have used them for years, incredible weight savings. You don't see aluminum radiators in towing vehicles, which stress their cooling systems and need to be kept cool, do you? Want to hear another fact that's going to upset you? If all else is equal, and detonation is not a factor, cast iron heads produce more power on a street motor than aluminum!

New cars primarily have aluminum radiators because of the weight savings also.

I had heard the thing about cast iron's superiority in combustion efficiency to aluminum before, and the reasoning behind it makes sense to me. Where were you when I posted about this and got beat up for it about a week ago?

I read a tech piece on radiator materials recently (sorry no link, I'm at my parents' house for the holiday). It explained the reason why aluminum is so much better than brass. I hesitate to try to post it, because I'll probably get at least some of it wrong.

The article explained that it has to do with the size of the tubes in the radiator relative to the material thickness required for sufficient strength. Brass cannot support the correct size tube because it isn't strong enough. I generally don't assume that something I've read on the internet is true, but when I see similar stuff several places I can be convinced. Also, theory and logic helps me!

Have a great 4th everyone!

Sorry I couldn't help with the iron-head beef but I've been busy b-sanding. I think I may be changing jobs, I could be a great thief now with no fingerprints left! Anyway, when you think about it, which radiator is best is actually a fairly lame arguement, since pretty much all modern radiators work very well, even the plastic-tank ones on GM vehicles these days work nicely. In fact they work a hell of a lot better than GM's transmissions, my Suburban just grenaded it's second one in about 20,000 miles. F'n chevys...

Ronstang · Jul 4, 2004

The most important feature of modern radiators is not necessarily the material they are made of but rather the fact that they have serpentine flow. I'm not going to get into the argument about copper/brass vs aluminum but I personally will never run a non-aluminum radiator ever again.

aluminum dissipates heat better than copper and brass, it's been tested. Ask a chemist about heat of exchange properties for the metals - you'll find out aluminum has a greater/faster exchange rate.
