Alumitech radiator selection

Was hoping someone may be able to help me out here. I have been doing some research on what the best radiator setup for my 72 may be. after reading countless posts, I have came up with the most common answer is an alumitech,, I did a search on them and came up with a place called UPI (universal parts inc.). They sell a radiator and fan setup for the chevelle, and the radiator is advertised as an Alumitech radiator. However I have also read that the alumitech company went out of business due to family priorities. Before I pull the trigger on this, I wanted to ask, is this the radiator that everyone was talking about ? Or is this another just using the name? I know how times can change, and wanted to get a little more experienced advice. I am posting the link to the radiator that I am talking about, I hope I am not breaking any rules by posting it, just want to show and see if this is it.

As always thanks for your advice and help fellas.

Re: Alumitech radiator selection

I dont think they are the Original Alumitech? The tanks are not stamped like on my alumitech and the other Alumitech I have seen. Maybe someone took the name and added a -?
As far as I know the original Alumitech company is resting because of the owner Dons family conditions a while back Don did a small batch of radiators.

Cold case or dewitt has great reputation and both looks like nice quality.

Re: Alumitech radiator selection

fixed your links, for some reason the HTTP parts were doubled up both of them.

The lower radiator hose outlet is wrong, it's given as 1.5" the chevy radiator has a larger hose fitting on the bottom. Don't recall if it's 1.75 or 2". The pic shows they're both 1.5". Anybody reading this remember? No idea why the upper and lower the same size. I'd look for a different vendor. These people haven't done their homework, these hose sizes were the same from 1955.

be aware that these aluminum rads will be wanting new anti-freeze every year or so to stay in good condition. aluminum being used is more susceptible to corrosion or something.

You might ask them how many rows of tubes and how wide are the tubes. 2 rows of 1.25 or 1.5" tubes seems to be adequate to about anything.

Re: Alumitech radiator selection

I replaced my Alumitech with a DeWitts because the Alumitech was leaking at the seams within 2 years. Alumitech had closed so I had no option but to look for another manufacture’s product. The DeWitts is higher quality, has a better shape in the tank stampings, the black finish is well laid, and it keeps the water temperature about 20 degrees cooler in 100+ temperatures with the AC full blast.

Re: Alumitech radiator selection

I was looking into the same thing ! Have you looked at the Cold Case line? They are a Sponsor here so that says something...they are not afraid to stand by their product.

Still using Alumitech in my Chevelle, been in there since before they closed down. Thing manages to cool my 565 but it's marginal in hot weather. It will usually stay under 205* after a pass and a slow trip back to the pits. In cooler weather it will stay under 190*. I always thought it a pretty nice piece. Never has leaked or caused any problems. I do keep it maintained.

Don alumitech worked for Dewitt before he opened his own company and bought cores from Dewitt Ive Bern told.

Mine is 12 years still looks like new both inside and outside, using peak gold anti freeze and a zinc anod still in new condition.
Also checks for electrolysis every year.
Can keep my 489 under 180 deg in head in 90+temps.
If I ever need a new radiator Im tempted to go with cold case.
