SB stroker guys - what fuel line diam and what carb?

Mines a 408 w/factory fuel line and a carter high volume fuel pump. I'm running a holly 780 street advenger carb. Just took it to the strip last week and put 7 runs on it back to back with no fuel problem at all. For my motor all that extra work of new fuel lines would be over kill. I Think what helps my car is that was used as a driver when I bought it. If you buy a car that has been setting up the line are probably full of junk. jmo
