Steve,

Do 50 Fords have that short flexible cloth covered rubber hose on the firewall that feeds the carb? Those hoses often detriorate causing blockage.

Do you have a fuel filter between the tank and the inlet side of your fuel pump. If not, you may be getting gas tank debris in your fuel pump that allows the engine to idle but, is starved for gas at higway speed.

Do you have any leaks at your fuel line/pump fittings? Is you fuel pump mounted correctly in relation to your tank?

Is the fuel pump putting out too much pressure causing the needle in the carb to remain "seated" rather than drop down? What about carb float height adjustment?
