Will the stock fuel pump on a 49-53 Flathead adequately supply a 390 cfm Holley? If not, I can order an electric fuel pump, but my plan for now is to use the stock fuel pump because I like the look. If I need an electric fuel pump, what are some recommendations as far as brand, capacity, etc. And what other parts would I need like some sort of regulator for it? This is a daily driver, not a hot rod. I just want a bit more air and fuel for highway driving.
