Re oil pressure.

My pressure gague read low (non-existant actually) at idle on my 68 2000.
I bought a high quality gague and hooked it up and I had plenty of pressure
at idle, the stock gague just was not reading accuratly.

So...before you start changing your oil pump it may be worth it to
determine what your oil pressure really is.
