Will my Carter 6903 120 gph mechanical fuel pump be sufficient for my 650 hp 528 hemi? I have driven it some on the street so far so good.(just got it done in the fall) I've done a couple blasts threw the gears no stumbles,but I have not run a full quarter mile shot yet. The car is a street car with 3/8 fuel line no return line and factory dual 4bbl 5/16 lines at the carbs. anyone else running similar power with a mechanical pump?
