Does anybody know the sweep on stock oil pressure gauge? i.e. is it 0 to 100 or 0to80 or 0to whatever. Thanks 4 any reply.

According to this link:

…mid way is meant to be a faked 40 psi. If you decide to believe that, then then gauge represents a maximum of 80.
Why not put a real gauge on it so you know what's happening for your car, specifically, then compare that to the stock gauge markings.
According to this PDF: http://www.sccoa.com/articles/thunderbird_1990.pdf
…'normal' stock oil pressure is 40psi ~ 60psi @ 2000 rpm
