<VV> Oil Pressure Switch Improvement

[Grams, Paul R. (ARC-T)]

Are there any Oil Pressure Switches that switch on at a higher pressure?  In the past year or so I remember reading an article in a Corvair newsletter that said NAPA had a switch that turned on at a higher PSI for better protection but I do not remember the part number or vehicle it was for or where the article was. Does anyone have any information on this?
