The QF 780 has metering block on the rear, the 3310 has a plate. The QF has 4 corner a/f screws, the 3310 has primary only. The QF has adjustable vacuum to the secondary diaphragm to control opening rate, the 3310 requires a spring change. The QF has replaceable air bleeds were the 3310 bleeds are fixed. The QF has throttle blade angle adjustment on the secondaries that is external and easy to get to. The QF is much lighter & made of aluminum, the 3310 is cast zinc (?).
I still like the classic gold of the 3310 best.
That's basically it. Oh, retail for the 3310 is about $275 and the QF is about $525
