Around 50lb @ anything over say 2000rpm, may even exceed the flow capability of the bypass when cold at higher rpm and get 60/65lb. Once warmed up 1000 rpm idle should be in the 15lb + area and around the 50lb area above 2500rpm. As the std pump is fairly well matched to the requirements of the std clearances it is not uncommon to find a normal running pressure in the 45lb range if engine is a bit on the 'loose' side.
