I have a 462 with Edelbrock D ports and old faithful roller cam. With stock fuel lines in my 70 GTO I could run the bowl dry on my quadrajet. Going to 1/2 line cured that.
So now I have 1/2 feed line and stock return. Holley 950 ultra hp and run a roddmc 550 pump and pick up. If I go up high in elevation and its hot out the fuel will boil right in the bowls and out the vent and flood out the engine.
I have a tanks Inc tank with walbro pump ready to go in to remedy this situation. I will also be installing a 1/2 return line as HWYSTR455 has suggested.
Anyway just one more thing to think about.
