Do all the Motorcraft 4300D spread bore carbs have the same flow rating?
I've seen 715 and 750 CFM claimed for the 4300D's. Anyone know which is
correct? Do the Boss or HO models flow more or are they just jetted
differently? I've also been told AMC made a special float for the 4300
carbs that changed the pivot some how to eliminate fuel starvation during
cornering. Anyone know the details?
