Just some tech info on the 8N: The 9N, 2N, and 8N's all used a 0-50 PSI Oil Pressure Gauge. The 80 PSI gauge didn't come out until the NAA Model, in September, 1952. Yes they will swap out no problem, and quite a few guys have the 80 PSI gauge on their N's. Anything over 45 PSI on an N means trouble. Ditto anything less than 10 PSI can mean a weak, worn out engine.
