What size fuel line is absolutely required?
-8 line [1/2"] would work just fine. I run my 67 Barracuda with 440" and 4.10 gears. [1/2" fuel line; then -6 split at the regulator to feed each fuel bowl]-[Note this is a 1050 CFM carb.] This car runs 10.70's @ 124 most all the time. [Through the mufflers on Radials]
