Newbie Power Steering Advice

I am awakening a 1956 300U that has been idle for years. I have read all the posts about the inadequate Power Steering and have disassembled and checked the steering box and valve body, but as my tractor uses the stock front pump for the loader and therefore has a GM Saginaw pump to run the steering - which is lousy to useless - I have the following question: Does anyone know the PSI/flow rate of a stock 300U PS pump? The Saginaw is showing 1000PSI cold and only 300PSI hot and the steering is rotten. I'm told the flow rate on the Saginaw is only 3 GPM at 800PSI. Is this enough to run the stock power steering? Can I mount a heavy duty PS pump from the racecar and put 1600PSI at 4 GPM and expect any action or is the PS system not equipped to handle a loader?

Thanks.
 
The PS pump on it now may be a bit small. (and certainly weak when warm) the 300 pump (on the engine right side) is a 1200 psi unit. (if good)
The steering system is not very friendly to loader use. ( I would put a Jackson power steering unit on the tractor if I intended to use it for loader work.) jacksonpowersteering.com. Other than that, I would use a better pump first to see if I could get by. I am not sure what the pressure from the factory steering priority valve in the hydraulics is set to run the steering. The repair manual, or others will know. JimN
