I believe most people recommend the high volume pumps.

buy the high pressure regular volume oil pump... if you read around on here you will find a few posts of a high volume high pressure oil pump sucking the pan dry during extreme conditions

Regular volume only. These motors already pump too much oil up top. Guys have tried running the DOD motor pumps on non DOD motors and have also run into problems. They are high volume and pressure. I like the standard GM pumps my self.
