Question type: Car Customization

How many pounds of fuel pressure do you need to run a carburated 5.0l ford, running with a holley blue pump, and a holley fuel regulator. The motor is also running with a performer 2 intake and a 650 holley double pump, the motor also has GT 40 heads and I believe a B303 cam.
