I installed a Cold Case in my 79 TA a couple months ago. I was having some overheating on the highway, 70 mph with a/c on in 90* weather, and the Cold Case cured it with no other changes. Great quality, polished, and fits like original. And reasonably priced. The tanks are thicker than the original radiator, like a 4 core radiator. So the cutouts in the original rubber mounting cushions are not wide enough. So you can either trim out your original cushions, or buy new 4 core radiator cushions. I bought new 4 core cushions. I'm using the original fan shroud and clutch fan, and everything fits perfectly. So, I highly recommend the Cold Case. I got it at Summit, since it was local to me. Good price and free shipping.

I put a Griffin in my 70 Formula looong before the Cold Case stuff hit the scene.
We have since experimented with a Cold Case in another car and I highly recommend them. Fit and finish is excellent, fin count is tight, and the core tubes are 1.25". Cools a 571ci Pontiac no problem in the AZ heat. Hard to beat for the price. |

Use your stock shroud and clutch fan with the cold case radiator and it will cool great.

I use the 28” Griffin. My original radiator sprung a leak so I got the Griffin we used on my stock car. That along with the big fan, a shroud and aluminum water pump, caused the temps to go down so far I had to put a 195 thermostat to get the engine over 160 degrees.

I recently installed the Frostbite sold by Holley in my 64 catalina. Fits good inside the stock shroud. Using the stock mechanical fan with a new clutch. It would get up to 210+ after extended driving. I haven’t seen it get past 180 after changing the radiator.

I put a Coldcase in my 68. It works marginally better than the 4 row copper/brass I had. It's mounting brackets moved the rad about 3/8 inch closer to the engine. This caused the fan to be fully inside the shroud, which, I have read here, affects cooling. 180 stat, 2600 rpm 60 mph runs at 175-180. Getting on it will still stay at 180. Old rad would climb to 195-200. After a run down the highway sitting in my driveway would climb to 210, same as old rad, where I shut it down. I'm hoping it will get better when I dial in the tune a wee bit better.

Installed a Rodney Red aluminum radiator in my 75 T/A in 2007 and have had great success. Three Hot Rod Power Tours and no overheating problems.

Oem spacer. The plan is to install a shorter spacer. Had to do carb work first.
