What is the GPH on a stock chevy small block?

I have a 600 Cfm holley on my 327 and it pushing over 400 HP, just wondering if a stock fuel pump isn't enough or do I need a more free flowing one.

How many GPH do you require?

Not quite sure.
I have a stock fuel pump on it now, the original style, but I am pretty sure it went out last time I drove it and it only has 2,200 miles on it.

How do you find out what is required?
