I have a 69 chevelle ss with a 500hp big block that I rev up to 8k rpm. what minimum size fuel line will supply enough fuel, so it will not starve? I am running a predator carb and an electric holley blue pump. thanks.......

I should think 3/8 would be good but I guess it depends on how your going to drive it. 5/16 may even be good.
Mallory recommends a 1/2" line for up to 550 HP. You might want to read this page:
