Looking to get a new aluminum radiator. Whats a good brand to go with and is it better to have the tanks on top bottom or sides?

ok, thanks Dom. I was just looking at a ECP engineered cooling products radiator with top and bottom tanks, lifetime warranty against leaks. Been using a side tanks radiator for the last 10yrs and was thinking I can get more exposed core area with top-bottom tanks. Whats the pros cons of side or top-bottom tanks?

Lots of good radiators out there these days. Summit Radiators were made by Norhtern radiator last I knew?!? Champion seems to have a good reputation and has direct fit for Mopars. IMO side tanks and cross flow works better than a down flow, top tank radiator does.

i use an AFCO , you do have to tig on your own brackets . been in for about 8 years no worries , daily driver and strip use
sideflow are less likely to block up and generally are lower profile .

I wanted the 1970 mopar radiator look in my car and not the generic GM looking or Scirocco style radiator in my car. SUPERIOR RADIATOR here in Michigan custom made mine to support 1000 streetable horsepower with dual electric fans. I am very happy with it so far.

I bought a champion for my 65 last year.150 shipped from Ebay/Fit was good cools great/i was leary as my OE rad worked great.More than happy with it.Even in the 90s it cools as good or better than factory.only thing had to make new upper hose and use a 1 3/4 adapter to 1 1/2 on lower.That was like 7 bucks.Very happy with it so far.Rocky

Looks like a few options here. So far what i have researched 2 row and make sure both rows are 1" wide. Some are not.

I bought a Howe from Summit and it was a decent price Cross Flow. If I were to buy another, I would look into the dual or triple cross flow, and definitely pick one of those.

I was looking at those early on but was told they plug up easily. I have a howe now but the in and out fittings are wrong for the big block.

The EPC is a nice radiator. As long as you don't care if it fits.


I was told it was bolt in...just check the print. I did and the print show the holes in the correct location to each other. They just don't line up correctly car.


So if you don't mind drilling some holes it's a nice piece. Just pisses me off I had to drill holes. They don't put the core in the correct location.

Those look to be very nice. I am leaning toward a downflow radiator as well. I noticed something a while back with my howe crossflow radiator. I had the cap off radiator and moroso pump running while watching coolant flow. The top 3 rows had no coolant running thru them at all. Coolant level will always be lower while running pump, so wouldnt a downflow make more sense as all the cores would be full all the time.

That's why I suggested the duel or triple cross flow radiators.

The water flow will find its shortest path. With Gravity assistance the Down flow rad will more easily find a shorter path vs a Cross flow rad. Witch means it Wont utilize the full surface area of the rad. So the cross flow will cool better, but the water will find its shortest path. Therefore, a forced duel flow or triple flow will cool better. But, with the proper fan cfm flow assist, any of the above rads will work.

I looked into the double and triple radiators.


I passed on them. I'm not smart enough to get all the science but I know the longer the flow path the less flow. If the tubes are big enough it will cool with out passing through the radiator more than once.
