Re: BBC temp creeps at idle; how did factory do it?

I went round and round with my truck running hot, something it has done since I met my wife 41 years ago, when it still belonged to her parents. Bigger fan, custom shroud (because the fan clutch is about 1/2" from the radiator, which is a different problem) severe duty fan clutch, blah blah blah. It wasn't until I put in a high flow thermostat that it was tamed. The AC compressor clutch shoe drags, so I have the belt off until I get that replaced. It doesn't creep up any more, and starts better hot- since it isn't hot enough to sear steak on the intake manifold, anymore. We'll see what happens when I get to that shoe and can run the AC again.
