Just asking, why does it have to be aluminum?

FWIW, yes, an aluminum radiator is lighter and less weight on the front of a Stude is always good.

No, from the experts with which I have spoken an aluminum radiator doesn't cool any better than does copper/brass. Copper is a better conductor of heat than aluminum. (Gold would actually make the best radiator, then silver. Copper is what we can afford.)



Maybe, discuss your goals and your thoughts on why you NEED an aluminum.

Thanks, Jack. My first thought at the heading was, why does he "NEED a (sic) Aluminum radiator".

I'll say in all fairness; an aluminum radiator that is about 98% plug 'n' play into a Lark type can be had for less than $200 vs. having the original unit rebuilt for $500+.

As per many others on this Forum; I went ahead and ordered up a 1972-86 Jeep CJ to SB Chevy V8 conversion radiator; drilled two holes into the front support and everything clears well. The petcock is covered up but that's no biggie since I can undo the lower hose if needed. Tranny cooler lines; that's a toughie since the Jeep AT line ports are also facing down from the bottom tank. I simply have my two lines connected together.

I really don't have a dog in this fight. I only asked in the interest of understanding the need. Your car, your decision, your money. However, a radiator on which the transmission cooler lines cannot be used is not my definition of "plug and play." Your results obviously vary.

BTW, US Radiator will make a brand new copper radiator which does everything correctly for a lot less than $500.

Last May I ordered an aluminum CJ-7 style radiator thru Brice Thomas Radiator, out of Kentucky ( Radman 2776 on Ebay. Contacted them via e-mail, they e-mailed me specs on the radiator, and then modified it to my specs ( moved the petcock, changed the size of one of the hose outlets all for a $25 upcharge). If I remember it was at my door within a week, undamaged it fit perfect, just had to drill the holes in the side flanges ( which they also adjusted to the length & height that I spec'd) I would at least contact them, they may be able to add the trans cooler too. I also added a flexilite electric fan in front of the rad that I manually control as needed, running a 350 SBC w/A/C.....it's working well.

Just a side note, Silver is a better thermal conductor than Gold (429 vs. 318 W/mK), and Copper (401 W/mK) is also better than Gold.
