Another fuel pump question ..

For the pump itself - Is there anything special for a 1970 440 pump I need to look for when buying a new one? (I should have mentioned before, but this is for a stock 440-6 setup)

What fuel pressure (or gallons per hour) should I look at for a stock 440-6 setup?). Are Holley's or Carter high performance the way to go ... or do the stock replacements from Napa, etc work for this setup?

I noticed some have screw-in fittings for the lines and some have hose nipples.. Any preferences on those?

Thanks a lot!
