oil pressure

so i purchased an 02 Z-28 with lots of mods, but the list of things done did not include oil pump...... what is the stock oil pressure of the LS1? i am at around 60 on the factory gauge while at idle.... here is a list of the engine mods-

Texas Speed stage 2.5 5.3L Heads
Texas Speed 228R Cam
Underdrive pulleys
Pacesetter L/Ts

my engine is stock. just have the pace setters. oil pressure on the guage is usually around 50ish at idle. goes up to 60 when on the gas a bit.

Yeah, 0psi oil pressure on the gauge would be a bit of a cause for concern.

My 178,xxx mile 98 Z28 runs at 20psi at idle (hot) and 35-40psi under freeway cruise. It doesn't make any noise so I let it be.

so i am under the assumption that my oil pump must be aftermarket due to the fact that when at operating temp. i am at 60...... with 15869 miles

Our oil pressure (hot) runs around 40 at idle and 60 plus up in the rev range. I always take the stock gauges to be an approximation at best. If there is concern, plumb in an aftermarket or master pressure gauge to check it.
