High Volume Oil Pump VS Standard Oil Pump

hi, if you install fill groove mains, a std oil pump will be ok. we found that a hv pump will in fact run a stock 5 qt pan about dry at the end of the strip.
oil pressure will be very low. thia pan had baffles and windage tray installed.
15-40 rotella or mobil delvac 15-40 would be oil of choice with .003 clearance.
plus they have the correct additives needed for cam life. comp cams recommends rotella 15-40 oil for their cams.
