Larry, I rebuilt my 79 1500 last spring with a stock pump. 75 psi cold, 45
psi hot at speed, and 20 psi at idle when hot. This is plenty of oil
pressure. Be careful with too high a psi you could blow out oil filters
unless you can get high pressure one. I don't know if they are available for
the 1500. You can also stress the oil pump drive shaft,
although the 1500 shaft is pretty hefty. If you go with a high volume pump,
let your engine warm up for a while before getting on it. I ran across the
filter problem on my 68 Mustang with a high volume pump. It pegged my 100
psi oil pressure gage when cold and I did blow out a stock filter. It came
apart at the seams!! The high pressure filter fixed this problem.
Good Luck,
Max Brewster
