oil pressure -- how much ?!

My 71 truck w/ an '85 350 shows ~ 60-70psi oil pressure when operating ~ 2k RPM, using a Sun oil gauge.

My 71 sub with a OEM 350 shows ~ 30-35psi oil pressure when operating ~ 2k RPM, using an Autometer oil gauge.

Both vehicles have the same type and amount of oil. Which one is right / wrong ? Will a high volume oil pump change the oil pressure ?
