Questions: NON-80 lb oil pressure gauge and speed-warning dash

[jocko]

I was looking at the really nice dash that PT's70CST has for sale, but didn't want to fod his sale thread - figured it'd be better to ask a question here and others might benefit.

I see a lot of hub-bub about the 80 psi oil pressure gage - what is the max pressure reading on the "stock" non-80 psi gage?

What exactly is the "speed-warning" feature and how does it work?

Thanks!
