Hello I am putting a chevy 350 bored .040 over and 270 advertised duration cam with alumiumn heads. The carb is a 650 cfm edelbrock. I am shooting for 400hp. The fuel pump is a mechanical 110gph. My question is do I need to run a bigger fuel line rather than using the stock inlet line? I would rather use the existing line for the sake of ease but I fear need a bigger line. Does any one have similar output and use their original line? It is a 1979 vette l-48. Thanks!

With my stock Tuned-Port conversion I am using the stock 3/8 line and the stock 1/4 for return. No problems.
