I have a 67 rs 327. My oil pressure gauge has always shown the pressure to be right in the middle of the gauge. Yesterday the guage fell when I was at a stop. It went back to normal when I started moving again. I check the oil level and had to add just a little oil. Is this normal? or is the gauge screwed up?

Sounds normal to me, your oil pressure will definitely drop at idle if you are a few quarts low on oil.......KZ

Thanx for the info kz. When I added oil it was about half a quart. Do you think there could be a bigger problem? I just don't want my baby to burn out.

1/2 Qt low shouldn't bee too bad, Oil pressure is related to RPM. At idle, especially with hot oil the pressure can be low. Somewhere around 10-20 psi. Maybe a little lower. The actual minimum psi required can be debated. if it is sufficient to overcome the crakshaft "centrifugal force" and travel from the mains to the center of the crankshaft, then it is sufficient.

When you acclerate engine speed picks up and oil pressure it will rise.

a good rule of thumb is 10psi for every K of RPM,

60psi = 6000
80psi = 8000

etc etc...
