Re: [AMC-list] Oil Pressure III

I agree.  10lbs of pressure per each 1000 rpm is what I always read as the 
acceptable norm for a stock engine.  I've never had any problems with mine.
I would think the stock low oil pressure sending unit probably has a spring 
inside that's designed for a minimum psi before it triggers the idiot light 
as is the case when initially cranking up the engine.
