I tested a 750 Mighty Demon on my 340 in place of the 650 speed demon it currently runs. The mid range and top end where awesome and the idle quality was atually much better.
The engine shop can get me a 650 Mighty Demon -all he says I need- or they also deal with Quick Fuel but he wont recomend the Quick Fuel because I haven't tested it. I like the idea of a choke but its not a deal breaker.
Which way would you go?

With that convertor and gears, I would go with the annular QF, and with the 340, they like 750's...I have one for sale if interested I ran on my 360, and it was awesome. Very similar set-up to yours....An annular carb is more responsive and acts like a carb that is 200cfm smaller than it actually is.
