Rusty, with the HV pump and the stock sized pick up tube you likely get more flow and pressure at low RPM’s. It would be at higher perhaps max RPM that a restriction to flow would occurr that a larger pick up tube would resolve.
I don't know. Maybe so. But how many of these guys are going to hold their engines at "that high" an RPM on a street car for "that long"? I do suppose as cheap as the pickups are, go ahead and get one, but what about the threaded hole in the oil pump? Same size.
