Ouch - $545! Another reason to go with a Modine.

That aluminum one has only 2 rows!

 

Copper is better and will last years longer, but if cooing system isn't abused and it's maintained right, alum will last many years also. Copper is also a better heat conductor.

Also, downflow is better than cross. Electric fans can be noisy when idling in some cars. If your cooing system works great with the crank fan, why add an electric?

I have a 3 row Modine copper and brass rad with a 302. I've sat in bumper-to-bumper on the 15 in the desert 115°F and the needle never went to half. I have a stock crank fan. I use an aftermarket tranny cooler, but the effect that that has on the motor temp is miniscule.

I haven't gotten around to it, but I am going to install a top hose see through filter. It keeps rust out of your rad, and they're washable. It will get better flow, work cooler, and the rad will last longer. There's only so many times the cores can be cleaned before they start to get holes.

Using less than 50% coolant is also a rust accelerator. If your top and bottom hoses don't look really new, change 'em when you install the new one.

Good luck, 390BB.

thanks, where can i buy a Modine radiator? or atleast look at the price difference i didnt like the price of the aluminum one either.

 

I just went to my local radiator shop and ordered it. They should ask all the questions to get the right model for you - have A/C? modified engine? etc.. I bought mine 11 or 12 years ago so I don't know what they sell for now.

VirginiaClassicMustang.com (540-896-2695) sells a '67-'70 390/428 Bracket Mount-3 row radiator....$310. I don't know who makes that one or what the warranty is but they are very nice to deal with and can answer any questions you have.

 

Believe it or not, I checked out Radiators.com and they had 3 row Modines for a 390 v8 Mustang from $200-$299. Modine is one of the top brands and have a name in racing as well as the street. I don't know about this site's service or shipping, but it's pretty easy to shop the net for rads, including ebgay motors. Your local shop can order for you and do the install, but at least you'll have some price knowledge. Good luck.

thanks for the site but im going to look for a local shop so i dont have to deal with shipping. And carlos your car looks sick with the side pipes.

 

There is some truth to the copper benefits, however the aluminum ones just have a much better design and truly do weigh a LOT less. A 2-core aluminum cools better than a 3-core copper, and sometimes better than a 4-core copper. Sometimes you get so thick on the 4-cores that it's hard to draw enough air through them, and the cores clog up easier internally as well as externally.

Definitely stay away from the "bonded" epoxy core aluminum radiators if possible, they do have issues down the road. Good luck with your choice, keep your coolant clean and run a good stock fan with a properly functioning fan-clutch and you'll be happy. 180 is a good thermostat temp, and see about getting a high-flow "cup-style" thermostat.
