63 dart stock car buildup 360/904. I have 2 coolers in front of the radiator. I was wondering if also using the bottom radiator cooling fittings in series would give me a significant gain as the hose routing on this addition would be a bit problematic but I would do it if a reasonable gain is there to be had. And the instructions said to use their (included) special hose but I might need more & it said fuel line is a no no. thank you for your time. RR
