For those that are modding their LS9's with heads, cam, blower work etc and leaving the bottom end stock for street use NOT flat out high rpm track oriented builds, are you leaving the stock oil pump in place during your builds or upgrading to the ported Katech pump for increased pressure and flow on the top end?

Any upside or downside to doing this on a higher hp (750rwhp) street engine? Thanks
