If you're confident about the dwell on the points and quality of the other components I'd probably verify the fuel system like Charlie says. You say you put in a new fuel line and pickup line in the tank. Had the car been running OK before, or had it been idle for a time? I'm thinking crud in the tank could be plugging the "sock" filter, or that either an in-line fuel filter or even the screen at the carb inlet could be partially plugged, blocking flow?
