Yeah, my electric stock gauge would fall on it's face if the motor was under 1000 rpm's. It turned out to be just the sending unit not reading under 1000rpm's.

Try getting a different sending unit.

Yup gauge first ask questions later! A drop in pressure at idle when hot is normal, but a tight rebuilt motor should still have 30 - 40 #'s at idle.

my oil pump is a racing oil pump i also put a gauge in it that uses oil pressure it has a line going from the motor to the gauge some people told me that the cam barrings could be bad the man i got the motor told me that he rebuilt the whole motor i got it from glen cylinder head in meridan
