Oil pump recommendations The Melling 10295 is what I'm thinking for my application.
5.3
7875 turbo
Summit Ghost Cam
Keeping it no more than 500whp.
The 10295 is out of stock on most websites. What is some other recommendations for an oil pump?

Have you checked at local part stores? I was surprised to learn that one of the O'Riley's near me had one in stock. I would think that one for a 2003 Silverado 1500HD 6.0L could be easily had at your local parts store. Rockauto.com claims to have a 10296 in stock right now which is a HV pump and the M295 pump would be just as good.

I’m using the
Blueprinted Melling LS1-LS6 Standard Volume Race Pump
Not sure exactly what advantages may have over a standard replacement. It was ported and had those aircraft wire tied bolts in it. But maybe in stock.

A blueprinted or ported pump, however, would be good as those mods ease oil flow thru the pump without actually increasing the volume.
IMO the ability to circulate oil more rapidly through the engine parts make HV pumps a plus. I have one in my LSX build which has standard bearing clearances with 10w and 5w30 oils.

Brett Foote I'd like to mention this about oil pumps. Any engine (without DOD, piston squirters, etc.) with bearing clearances at approximately. 002"/.0025" will flow x amount of oil@50lbs pressure. You could mount a high volume pump that flows 30 gallons per minute@50lbs pressure, and if the bearings pass only 10 gallons per minute@50lbs pressure, then 10 gallons per minute it will be, I don't care how high volume the pump is. Where guys get in trouble is they take a high volume pump, and then add a higher tension relief valve spring. Upping the pressure changes everything. It is conceivable you could then pump the pan dry with enough rpm, time at WOT, and if you have a stiff enough spring. With enough rpm, you could conceivably do that with a standard volume pump that has a much stiffer than OEM relief spring, and never do that with a high volume pump@stock pressure. A high volume pump with OEM pressure does one thing for an engine that the OEM pump with OEM pressure can't. That would be to regain oil pressure quicker if high g-force cornering has caused a cavitation issue. Stock pressure for the LS engines works in 99% of any situation. There's no good reason to exceed 65lbs pressure.....
