I wasn't about the pump. I agree with the HV pump, but why the need for the oiling mods drilling out passages in an otherwise low RPM engine? That's what I don't understand. ....but again, not my circus, not my monkeys.
Doesn't hurt anything... And it might help ensure adequate oil supply to help reduce oil temps in low flow areas. Not sure where they'd be in a BB, but I know OEM passages were designed more for budget and daily driving than they were for HD use.
It's also worth noting that we measure oil pressure at one spot, it can vary wildly in other places due to clearance sizes. Bugger feeds ensure the pressure stays up until it can't anymore. Which should result in better longevity. Maybe. But the worst and only drawback is really the time spent to do the drilling and modding. So why not?
I think at high revs the mods become a requirement, whereas at lower revs they might help some, especially with sustained load. But also maybe not 100% required.
