Re: fuel line bbc

More than enough. I ran a 454 ~550-575HP with a 3/8 line, AFR did not lean-out during all my 1/4 runs (I have an AFR meter in the car).

in most cases yes!, of course fuel line fittings, used, filters installed and cheap fuel pressure regulators, with restrictive ports could potentially restrict flow
