Something to keep in mind on the oil pumps, while the motor is set up to run a full pressurized system, the oil pump drive mechanism is marginal.
The stock Mod "A" had a transfer pump, not a pressure pump.
If you attempt to run too much oil pressure, it will prematurely wear the stock drive unit.
I have found a moderate pressure works well with stock drive assembly. If you think you are going racing it is wise to use a pump driven off the cam or a belt from crank.
