I see all the help on here and am at my wits end(not very long)I've been helping a freind with his falcon and give up ,,Hope you guys can lead me to some new pointers,,here goes
65 falcon 260 3 speed(manual trans)new engine(5000 miles) has just developed a "hiccup" only while cruising at high way speed 65mph ..it occures when a slight hill comes or when lightly applying more throttle,if you step on the throttle harder it doesn't do it,,, it doesn't do it around town or at slower speeds after hiccup it takes off fine but will continue to do it when you resume the cruising speed,,
I have set timing,adjusted carb,checked choke,vacumn and fuel supply and float level,,I took the carb off my vert installed it on his car and it still does it,,we replaced distributor,installed pertronix,and plugs,checked the cap and wires,,HELP please give me some new leads to chase

I would have thought distributor or carb. Since you've tried those, it's probably starving for gas at higher rpm's. I'd put a new fuel filter in. If it still does it, I'd try a fuel pump.

The hiccup is more a miss fire than a back fire ,,It can't be starved for fuel at high RPM because it runs fine as long as the throttle is wide open
