I was just looking at 440Source for the distributor driveshaft and found something Disturbing. They are selling in Their own words "Heavy Duty pinned Intermediate shaft - Steel gear (needs slight grinding of hex flats to fit pump) $25"  "Needs Slight Grinding of the Hex Flats to fit the Pump"  That doesn't sound right to me !!! Wouldn't the shaft be case hardened and would not grinding ruin the hardening ???
another QUALITY PRODUCT brought to you by ....  ...
If you are going to run the HV pump it would be a good idea to install an HD drive, and one you don't have to grind to fit ....
that's too funny , you can't make s.... like that up ...

Some good points made. My use of them has been on daily street driven cars with mild motor mods, cams, headers ect. Not cars that see the upper RPM's all time time. My reasons for using them was for more low rpm,s such as idling for 15 min in a drive through. Not WOT all the time. Sure they see a few burnouts and WOT for a few sec on the highway but not for a living.

I would tend to think that extra PSI would increase bearing wear.
Never heard that before, care to explain?

Not much PSI is needed at low RPMs and especially not at idle where there is no load on the engine.
Long idle can starv the cam and valve train so I've heard. Isn't that why cam break in requires 1500 rpm?

Those who say they have never ran out of oil with one and a stock 4-5 QT pan has never run there car for a extended periods of hi RPM to know.
My 
I'll have to be the one I guess.
I've had tons of vehicles with HV pumps. No deep pans.
10W30 oil, windage tray and a quart over full. Did it for 30 years, ain't gonna change now either.
My Jensen is a stock pan, windage tray and runs a quart over full of 10W30. I beat it senseless all the time.
My Charger is a stock depth pan, windage tray and a quart over full of 10W30 weight.
Running 20w50, no windage tray and stock oil level isn't MY idea of "an ounce of prevention"....
 In fact when the windage trays were made available service reps advised running an extra quart. I seem to remember that it was also in a FSM but wouldn't swear to that. Not to prevent the pan from being pumped dry but to prevent oil from being pulled away during launch or hard braking.

My 383 Valiant 4-speed with stock pan and pump would lose oil pressure momentarily (idiot light would come on) whenever I launched at 3000 rpm or higher... A deep pan and windage tray fixed that

Just thinking about more pressure and how that might erode the bearings over time. Just a thought.

Cams get splash oiled, not pressure. Valves, you may have something, but who is idling their engine that long on a regular basis? In a hobby car I'd guess not near as much as your DD.
