I figured I would post this question here since there are quite a few racers who hopefully will give me some insight.
I have a 1965 727 that was rebuilt and it has a 4 quart aluminum deep pan. The trans is going into my 64 Polara with a 3 core 22in radiator. The torque convertor is a PTC 3500 stall, and the rear gears are 3.55 and a 28 tall tire. The convertor was recommended to me by the trans builder. Since I plan on making some trips which are about 100 mi away, I did some preliminary math and I am around 3000 rpm at 65mph. So needless to say I dont want to cook my trans, and I want to add an additional cooler. I came across these 2 from Derale, and they are quite large (11 in across)and I am concerned that since I am blocking half the width of my radiator, could I run into engine overheat problems in town? Or is this over kill for a trans cooler, would I be ok in using either or? Or does someone have a different option of what I can use.

Since I cant find plain Dextron anywhere, and I was told NOT to use synthetic fluid, is this ok to use?
Thanks for the input.
