Oil pressure is crazy high!

It seems like, hang on a second........:soapbox: OK. It seems like the hv pump is considered a no brainer on any rebuild! Could someone please explain? Folks are buying HV before disassembly??? I have seen no reason to question chrysler engineers, and oil has only gotten better. A buddy of mine is building a 56 belair right now. He asked me the other day: What hv pump should i get? To which i said: Are you running a stock pan? YES How high are you gonna buzz it? 5500-6000. What are your oil clearances? DON'T KNOW. What oil are you gonna run? NOT SURE, i was thinking about blah,blah,blah. Talk about monkey see monkey do! I don't know about BB chevies, maybe they have some kind of oiling issue from the factory. Then he'll be whining because he can't keep the damn thing sealed up! I'll get down off the box now. I just thought it was all about demand and supply.
