HV oil pump vs Stock oil pan

The simple answer to the op's question is yes, you can run an HV pump in a stock pan and on a Mopar, it'll never, ever drain the pan dry. Also, since the subject has SINCE come up regarding the use of roller lifters that use more volume for direct oiling to the rollers, I think the HV pump is a good idea. I originally said to put the high pressure spring in a stock pump, but since the fancy roller lifters are in play, I would use the HV pump.....and probably still put the HP spring in it. Remember, they don't come with the HP spring automatically. I believe if I remember right, Mopar Performance was the only one to offer pumps that were both HV and HP. I have a big block one around here somewhere still new in the box. There are some really BIG name engine builders both on and off this site that use nothing but HV pumps in their builds and they have no issues whatsoever.
