Anyone had any dealings with the radiators from speedcooling.com? They list a 22" and a 26" radiator for small block. My 74 360 duster came out with a 26" radiator. Since I installed a/c, it wants to run warm on a hot day when I'm using it. The radiators they list dont list what bodies they fit. Are they all the same? The blueprint dimensions on the webpage are really close to the aftermarket radiator I put in it over 20 years ago. I dont have the factory original radiator anymore. I think the one I have is a little shorter than the original by looking at the way the shroud fits it. The one I have has 1/2" cores 9/16" apart 2 core. The aluminum ones from speedcooling are also 2 core but have 1" cores but not sure how far apart.

The old copper/brass one I have will run about 195 without a/c. With the a/c on yesterday (94 degrees outside) it wanted to run about 210 running 60 mph. It would cool down to 195-200 while idling up to 30mph. I'm guessing I dont have enough radiator by it doing this. I am running the factory shroud. After installing the Classic Auto Air kit, I also installed a seven blade fan from a factory a/c 71 duster and the correct fan clutch. It moves lots of air.

I know Im kind of windy but want to give all the information so everyone can help me before I spend the money. I like the ones from speedcooling because it looks like they have a more factory looking tank on them.

Thanks guys.
