Fuel Pump Question

I have a 1973 Plymouth Duster with a 360/380 crate engine and I am just trying to decide what kind of fuel pump I should get. I have a low end electric fuel pump right now, and it has a hard time pumping the gas I need. So I was just wondering what other pumps people are using and what some of you would recommened. Also what gph rating i should look at getting. Also just any other suggestions on the way to improve the whole fuel system, besides the electric pump it is a stock fuel system. Thanks for the help.
