Fuel Pressure For 720hp

What is the correct amount of fuel pressure to run? I'm running Aeromotive electric fuel pump with edelbrock mechanical fuel pump feeding an1150 Holley Dominator carb. Naturally aspirated. Thanks

i would run it shy of 7psi,,you need volume,dont plan on using a 3/8 fuel pick up and fuel hose to keep the catb full..i would get rid of the mechanical pump and run electric with a regulator and a bypass hose back to the tank..1/2'' hose minimum..

The desired fuel pressure for all carbs is virtually the same. Ideally, you want to see 6-7psi in all rpms.
