i have a 2800lb 64 falcon 393 Windsor and a four speed. 12:1 ,pro comp 190cc heads with 1.94 2.02 valves. Single plane high rise. 305 duration .540 lift flat tappet cam. It's a race engine. I'm running a 750 double pumper and am concerned I'm under carbureted. What size carb are you guys running on your ford stroker drag race engines? I'm not running near my potential. Only 1.64 60' times. I'm hooking up. Just seems lazy. Mph sucks.
