Fuel line? Is it enough

OK here is what I have , 72 duster "H" code previous owner put a 440 in it. Now I built the 440 and its now got aluminum heads, bigger cam ,bored 40 over with 11 to 1 compression. Is the factory 5/16 line going to be enough to teen the roughly 550hp big block? What's everybody's opinion? Any help would be appriciated .
