Gm part # for oil pressure switch for 97 ss

Does anyone know the gm part # for the oil pressure switch that is located on the back of the intake manifold. This is for 1997 lt1. Thanks

1993-1997 F-Body Part Number Collection

It's way down toward the bottom of the list.

What is normal oil pressure for a lt1. On cold startup I get around 40 psi and hot idle I say 10-15 psi.

Fairly normal for an LT1 engine with medium/high miles on it, assuming 5W-30, or 10W-30 oil. New LT1 engine would be 30 PSI fully warmed up, 650-800 RPM idle.

There was 10w30 in the car originally i switched to 10w40 and seen no difference in change in pressure. That has me to believe it might be the pressure switch going bad. Car has 114,000 miles on it.
