Fuel lines for my 70 Dart 440 500+ HP??

Sooo... I am also about to Put new fuel lines in my 70 dart to accommodate a 500+HP 440 motor, I think I want to run 1/2 fuel line 8AN is that recommended?
Can anyone recommend where to start and what they did?
to start,..do I change the fuel sending unit in tank to 1/2'in and run 1/2 line with a fuel filter all the way to fuel pump then from pump to regulator then to carb?
Im also using a carter street strip mechanical pump.
