Question about A-bodies with Rallye Guages.

Can anyone tell me where the Rallye cluster oil gauge should read under normal operating temperatures? The pointer in my guage reads about 1/4 of the full sweep. I have a high volume oil pump and figure 40- 50 lbs. should be the output. Magnum 360 engine.

I'm asking because I haven't used this gauge in a long time, had a mechanical Gauge previously . New oil pressure switch BTW.

Thanks for any help
