Fuel pump Help!

Ok i have a 406 SBC that should put out at an area around 550 HP and i need to know what kind of fuel pump(preferrably mechanical) I should get. I dont know much about fuel pumps so maybe you all can even spec me out one or just tell me what i need to look for.

Carter M6900, or a Carter M4891 with an external bypass regulator.

No. But they need volume, especially a higher horse motor.

Mark.

Too much fuel pressure on a carb is a bad thing, the floats can't control the fuel level in the bowls and they flood. Around 6 PSI is about normal, much more than that and problems start.
