More recently I'm running 180 lbs. in my metrics, without smearing the frictions or any thrust bearing problems. I've known some racers to have less line pressure and a few to have more, what I'll say is - what line pressure works for you without destroying parts is best.

While the info you provided is good, I don't know if a Torqueflite can be compared to a Glide or TH. I've never run more than 140 psi in a 'footbrake' 727. A transbrake 727 usually needs 150+ depending on who's brake is being used...then I've heard of people running as much as 200-220 with a brake. I was always under the belief that you should run as little line pressure as you can get away with.
