The oil pump is driven by the distributor shaft, so the faster the engine goes the faster the pump spins.
To answer the question, yes, the oil pressure should go up and down with engine speed.
The oil pressure gauge will fluctuate on a Chevy Tahoe when the vehicle is idling and when the vehicle is driven at highway speed. Idle is usually 30 psi oil pressure or slightly more. At highway speed, the oil pressure should be between 60 psi and 80 psi.
The old rule of thumb used to be 10 lbs per 1000 rpms. So, if that old Chevy small block engine is warmed up and idling with 10 lbs of oil pressure, don't worry about it.
You should check the timing and plugs.
It should be idling at approximately 625 rpm while the engine is warm.
If you are asking what the pressure should be, it should be 5-6 psi but we really need to know what year and engine that Chevy has to correctly answer that.

NO not that engine.
The fuel pressure should be 45 psi .
The fuel pressure should be 45 psi.
Fuel pressure for a 2003 Chevy Monte Carlo should be between 50 and 55 PSI. This ensures that the injectors will function properly.
