What Fuel Pump?

Was hoping for some help on which mechanical fuel pump I can use on my Magnum 360 swap.

I have airgap type intake, stock 1994 Magnum bottom and top end along with original cam.

I already swapped over my LA 360 timing cover, chain, water pump, pulleys, etc.

I have also aded the cam snout extender with eccentric.

So all I am trying to figure out specs on which mechanical fuel pump will work best on this setup.

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.
