Yah, I didn't even think about it when I replied, but looking back the fact you quoted PSI was a clue. I have the numbered oil pressure/temp gauges in my '77 too. Love 'em...

I very may just up-spec the oil pump in the coming christmas break anyway. time for some more research.

930 pumps are very spendy now. Also NLA, I believe. The factory went in a different direction with the later high-perf pumps - e.g. for the GT cars, which I believe is the superceding replacement part. IIRC, they have less flow, but more scavenge.
Check the engine rebuild forum for detailed discussions/fitment info, but you'll probably need to clearance the early case to fit a bigger pump. Don't think that's a precision job exactly - although re-assembling the case takes some skills, of course.
If the 3.0 crank uses the same 9mm rod bolts the 3.3's got, upgrade to ARP as a matter of course at the first opportunity would be my advice.
