Lots of variables - RPM, clearances, etc. Quality and viscosity of oil can also be factored in. But I've been using stock p/u's in my current car since 1999 with Amsoil viscosities as low as 5w-30 with no issues. 6,700+ regularly and the pump is OEM pressure & volume! Oops! Make that 5w-20. Very mild porting/polishing of the OEM passage in the pump and main cap can help a bit.

My motor starving for oil. The book "How to build SB engines says that the pick up tube is too small. Will two pick up tubes work.
lets hear all your views, Please Thanks
There is a reason for all things mechanically that fail, why is your motor running out of oil? Fix that and go on and have some fun. Maybe we need some more information as far as what your doing,IE drag racing, street, truck pulling, circle racing or?

My first question would be what oil pan are you using? I and several friends have used a blueprinted stock pump in many combo's with success. Are you using a Hi Vol pump and the oil not draining back fast enough?

It takes a lot of oil to keep up with the 360 main bearings. I have had shops try to set it up with too much clearance and it would pump the pan dry with a high volume pump. Alway ran a high volume with the 360 mains I ran. I would however try a standard pump with 340 mains.
Are you sure the plug in the drivers side rear of the oil galley is in place. I have seen many left out and had big problems. I also ran a roller cam with the oil galley tubed. Ran Harland SHarps and restricted oil to the heads also. Holley #66 main jet works great on the Passenger side and #72 on the drivers side. The cam I ran had the journal ground to oil the rockers full time. Spun that puppy 8400 in the quarter with no problems.
I think you have clearance extremes or oil control problems that are not getting the oil back to the pan. Wait, truck pans are only 6 quarts. Will a KEVCO pan work they are bigger. Probably 8 quarts.
Another thing if you are running too much ignition timing you may be beating the oil out of the bearings.

Well that is an interesting question, 'Is it not draining back to the pan?" How would I know ?? Its a stock truck pan. no mods to it.
11 second car, about 6500 spinning, foot brakin. The bearings show flaking and the typical signs of starvation. New HV pump
Is it baffled????
True ... all the pans I make have baffles to keep the oil at the pick up

If either one loses prime, the other one stops pulling oil.

it looks like your treating the symptom and not the root cause. solve the oil pan issue, the drain back issue and make sure you have the proper oil clearance for the bearings and the stock size pickup will be more than adequate.

http://www.forabodiesonly.com/mopar/showthread.php?t=103623BTW there is 9 quarts of oil in the Canton 7 quart pan and the level still shows to be 1/2 quart low on the dipstick from the stock oil level.
