I recently installed an oil pressure gauge on my 55 Fairlane.  It has a 272 that was rebuilt prior to me owning it.  I installed the fitting for the gauge in the block, just to the right of the oil filter and used a new Autometer kit with new fittings and nylon line.  Upon startup (cold), the gauge read about 70 psi which seemed high to me.  I drove for 15-20 minutes, and the gauge read 60 psi the entire time while driving.  It settled in about 40 psi at idle.  The next time I took it out for over an hour, including getting up to highway speed (70-75 mph) to see what it would be when the engine was hot.  Running pressure remained at 60 and idle leveled out around 30 psi.  I guess I was pleasantly surprised, but I wondered what everyone else has for cold, running hot, and idle pressures.  I'm interested because my 292 in my 59 F100 is always 60 cold, 40 running hot and 25-28 at hot idle.  I've been running that motor for about 8 years since I rebuilt it.
