pressure 50-65psi at cruise or under acceleration
oil 190-215 is best
coolant, about 15 degrees below the oil

These are the exact numbers I get on my 85 with a 180deg stat and the fans set to turn on at 200deg.

Oh No, I have 45 psi of oil pressure cruising and 13 to 15 at idle when hot (180). I guess I know my next project or just add it to the list. :rolleyes:
