Question about fuel lines?

[6camaro9]

I am getting ready to redo the fuel system on my camaro and was wanting to know what size line would be best to use -6an or -8an. I am currently running a 400 small block with a Holley 750 carb. Thanks

I believe the 3/8 line would be plenty. Now what that boils down to in AN measurements would be the -6.

I'd wanna do the lines once so if you have power goals that are much higher sooner or later, maybe plan with that in mind and it may want you to do -8?

I have a LS7 w/ cam, intake, long tube headers and tune running -06 fuel line with zero problems.
