Hi volume oil pump vs standard volume pump

Same 340, went from 72 hv to m72.....no pressure difference on the gauge what so ever.
I took the advice to ditch it, that it ate almost 10hp by 6000 rpm. I dont bother with hv pumps anymore.

I like the front main tighter than the rest, I like full groove mains, m72 pump, milodon pickup and deep pan, I like to use a windage tray 'even with the deep sump' they still help and if you use a thick milodon version... they act like a motor blanket as in they'll save your 350.00 oil pan from holes if you lose a piston or shut it off soon enough with a rod....just ask how I know.
