Thanks for the info guys, as always great help here. I have a 67 Firebird Sprint. I dug out my Pontiac Parts Catalog, for sending units it only list a number for an 8 cylinder however if you look up the rally oil pressure gauge there is only one part number.
My car has an 80 PSI gauge in it which I'm pretty certain is original to the car. Had the car since 1988 and it had gauge from the factory.
I'll go with an 80.
Thanks, Rick
