I used to have a mechanical pressure gauge.. It was the normal test gauge you hook up when your installing it.. I had it zip tied to the winshield wiper..
Since then I have installed the electric gauge (industrial gauge).. When cool (e.g. not over 120F) I get about 100 or so psi at idle in park.. Reverse is about 160. And it moves about the instant I hit the throttle.. At 70mph (2250 rpms) It sits at about 160 psi..
When warm (120F or so) the pressures drop at idle to close to 80 and the 160 cruise on the freeway drops to about 150..
I can dig up my test sheet form when I installed it if you need the exact numbers I got. My new electric gauge doesn't have enough marks on it to get exact (e.g. 100psi is between 80 and 120psi).
Also, my temp gauge isn't mechanical.. Its electrical, but a 270 degree sweep marine gauge that uses an amplifier. The temp sender is in the pan.
I do have 2 coolers, a plate style first (15k gvwr) and a tube/fin style (20kgvwr I think). I don't run it through the radiator heat exchanger. It doesn't get cold enough here in Southern Az.
I have a pusher fan I'm going to be installing in the next couple of weeks that will run when the converter is not locked to see if I can get the temps down some.

edit: Actually, those pressures don't drop until the temp is a little higher.. closer to 130-140
