Oil pump question I have a High volume oil pump that I already ordered, The only thing is i have a stock oil pan, if I just add an extra quart, will this keep the pan from running dry, because I have every thing off and ready to go.

the general consensus is a high volume will suck your pan dry. Unless you have some major bearing clearances a high pressure one is more than adequate. BUT I used the excuse of having a melling select 10% volume to get a canton pan.
I wouldn't add any extra, the oil sloshing around the reciprocating assembly isn't good

I did heads and cam on my 96 impala in 07 and installed a melling select pump #10551,hv hp.Stock pan no extra oil added and it is driven hard daily.It has 50 psi at 80 mph and 25 psi at idle hot,65 psi at cold start.I don't think any pump can pump a pan dry.

I just recently removed my Melling chinese piece of garbage and bought a Titan. If you are going to stick with the spur/gear style I would go with a high pressure pump and stay away from the HV version.

If you go with the HV pump, be prepared to periodically remove the intake and inspect the drive gear. I don't know of how many threads I have read where people were shocked at what they saw. Of course, some had loss of pressure because of a shredded gear.

HV oil pump, IMHO, is not needed on a "stock" bottom end.
If your builder sets up your bearing clearances so HV pump is of designed benefit, fine.
I have a 383 with the HV (builder set bearing clearances for one) and a stock pan.....don't subscribe to the "it will pump the pan dry" concept....
I did have my intake off 10k miles after build...no "visable" sign of drive gear wear nor has there ever been metal shavings in the oil.
I respect opinions by shbox so I can not discount is notes....just in my case I have not experienced drive gear wear or noticed the pan getting sucked dry...at least OP not indicateing that happened.
