I can say this about a typical out of box carb from say holley/bg/qf, more often then not a new to alky user is unhappy with them because normally they do need tunning help. That being said possibly look into some others you may pay more up front but well worth it in the end.

ww.apdracing.com
& Pro Systems comes to mind.

just my 2 cents

ruppert & apd is what i use, you need to buy a carb or send one off and have it built for your engine.you'll be alot happier.good luck

I would not suggest the proform carbs, but I know a couple of guys who dynoed with quickfuel and they had to do quite a bit adjusting to the carbs on the dyno to get better numbers out of them. I bought a new Pro Systems carb and I had to jet up the secondaries two sizes is all. My carb made excellent numbers with the Pro Systems carb.

I know this is one way or the other either the 750 has a 850 main body or the 950 has the 850 cant remember which. Either way I know a very good carb company that redid one for a buddy told him he was wasting his time with it.

The best carb guy I know says they are junk
I've seen it proven over and over at the track he is correct :D
