I've read something about that in I think mm&ff, but like others have said, I would not do it on a daily driver. I think they only gained like a couple of hp, not worth the risk.
Not to steal your thread, but here's some food for thought... My buddy was driving his 88 GT home from school one day and it started making this odd exhaust leak sound. So he thought. Turns out the oil pump drive shaft had twisted and snapped off. Drove it about 10 miles home and then ran it a few different times trying to figure out what was wrong before he found it. It had about 110K on it then. Now it has over 135K on it, 9 years later. I wouldn't reccomend anyone try a stunt like running it without oil, but if the pump isn't spinning and it didn't do any damage, .5 or 1 quart low won't kill the average 5.0

The same thing happened to me. Somehow a little chunk of metal got caught inside the oil pump and snapped the driveshaft. I drove it 10-15 miles as well. I figured what saved it was the prolong additive though. Maybe 5.0s are just that tough? The motor had around 180,000 on it then, 230,000 now. On the other hand I've seen chevy motors let go pretty quick with no oil pressure. (not anti chevy btw)
**** my lifers went in mine so i thought it was out of oil I added a quart and it was full. So i wouldn't do it I try and keep and eye on my oil now lol don't want to repalce them again just yet
