What Fuel Pump?

I am using an eddy 604 performer series, 600 CFM carb.

Will a stock oem 360 fuel pump work. If I am not mistaken those run anywhere between 6-7.5 PSI at around 30 GPH

I read somewhere that the Magnums with airgaps like to be more around 4-5 PSI, any truth to that?

Thanks.
Intake doesn't care, your fuel induction cares- in this case your Edelbrock carb. It should be below 7- below 6 would be better for an Eddy, 5.5ish'd be good.
