A bog is usually from a lean condition and a lean condition will cause heat.................a bog from rich will be pretty apparent from the smoke.

Thanks Don,

I will provide more later today but in hurry now. Going to work.

The Rad is not 1 1/4 thick. Its core's are 1 1/4 thick. Times 2

Does it boil over? 210 really isn't that hot if that's the max it hits. Many of the old GM cars turned the fan on at 108C which is 232F degrees I believe. Admittedly an engineering screwup but they wanted those engines to run hot for emissions.
Anyway, this might be an arguable oversimplification but if it doesn't get hot enough to loose coolant then you really don't have a heating problem. I agree that a 2 core might not be enough radiator.

5500 in third and a bog when you lock up? I am having a hard time visualizing why you even know that. What kind of driving situation encounters that in a 4x4?
Not hacking your tranny guy per se but you generally get what you pay for and if you bought a cheap tranny chances are good that you got one. The only 700R I drove much would overheat quite easily on a long pull when the converter was unlocked.

Thanks Billy,

Well 210 is the point I will not allow it to exceed. Will it go above 210? I dont know. I wont allow it a chance to get any higher. My money means to much to me. As for the tranny cheap is not a question. I did get what I paid for. Built to my specs. I had the converter made to my specs too. You have never seen 5500 rpms in third gear? Ever been to the track?

The Tranny is in no way under question from a heat standpoint. The Tranny temp is under control. I have coolers in place to take care of that. I understand that a non-locked converter makes more heat.

When you modify a tranny to allow you to lock the converter when you want is allows you many things. I really dont want to explian it all now but I think most of you know what I have done. With knowing that you dont know how or where I got my tranny I wont take offense considering I offered to hook anyone up with this guy to build them a tranny I will say that my tranny guy Wayne has built the trannies for all my projects for the last 10 years or so and when I have him build me one I make the trip to his shop and pick them up myself.

I am really think I will look into what Shawn has said about running a bit lean. I think I will check my jetting out and see where I'm at. I might have jetted it lower than I thought I did.

I didn't mean to offend you, the part about getting a "cheap" tranny was an observation. Cheap and good are generally not bed partners.
Yes I have been to the track but just not in a 4x4 I guess.
If you are running a 12-14 psi rad cap you can run up to 225-230 without being in any danger of damaging something. On our dirt cars we usually ran a 22 pound cap and considered 250 to be shut down temp but if you were in the lead and got the white and it was on 250 you would stay on it for sure.
I think every 1 psi raises the boiling temp 2 degrees, can't remember for sure.
Also consider the coolant. 50/50 mix is the standard but water has better thermal conductivity that antifreeze, but then antifreeze has a little higher boiling point. We have used a water wetter agent that breaks down the surface tension of water and lets it conduct heat better on race cars
