Also which pump should i get?
GSS307M
or
GSS340M
I assume GSS340M is to much for a lightly moded 350.

I'd get the 340 (did actually). I got it because I plan on going to forced induction later, but for an extra ten bucks you might as well upgrade. Besides, gives you a little room to grow...

On there website it says the Walbro GSS340M pump is rated at 60psi+. So it won’t matter running it at 40 PSI? I don’t ever plan on upgrading to a blower or anything but I do want a really good pump.
Is the only difference between the Walbro GSS307M pump and the Walbro GSS340M pump pressure? Or will one last longer or something?

All I want to know if there is such a thing as having too powerful of a fuel pump. I have a 350 with the modes in my sig and I was thinking of getting the Walbro GSS340M is that too much for my engine???

The GS340 pump with the hot wire kit is good for 10's 
Oh and the GS340 flows at 255 liters per hour and at 50 psi with 13.5 volts applied to the pump it flows @ 65gph
