Not firing up!?!?!

I have the same issues going. Mine is a 65' cuda with a 273 V8. I started with battery,plug wires,plugs,cap,rotor,points,condensor,coil,starter,starter relay,voltage regulator and resistor. New resistor started smoking soo that was swapped back to old. After all that i still had rough idle and lack of power. Then went on to the fuel system by rebuilding carb and adding new fuel filter. Still rough idle and little power. I have a new fuel pump to install and hope that helps because if not I have hit a wall. Any advice?
