If I am in park it sits at 900rpm. If im in drive with the brakes on its sits a lot lower. Its always been like it.

Might be time to re-set the base idle in that case, simple enough job, Haynes has the procedure for doing this.

V8s do run with quite low oil presure, limited partly by the drive gear on the dizzy.

What model gauge did you use and where did you plumb it in?  any chance of some pics as I was wondering about fitting such an item as I never did like trusting a simple on/off warnig light!!

Depending on the model year there are 3 tapping in the oil pump, be careful as one is the prssure relief valve.
