I have a 355 Crate with a Quick fuel 650 in my 73. The fuel pump went south and I replaced it with a holly electric. Due to the noise I have decided to go back to a manual and need a recommendation on a fuel pump. Will a stock pump have the gph to do the job.
It will depend on your engines demand for fuel and how you are using your car.
You don't want it to starve for fuel when you nail the throttle.
You should also run a good regulator set for your Quick Fuel carb.
My Quick Fuel regulator is set for 7psi per their recommendations.
Call Holley tech services and get their recommendation for the pump.

This is the best choice. I have an AC Delco stock replacement pump (dirt cheap from rockauto.com) on my 383. I've gone 12.15 at 110 mph with it. No problems.
