Whats my best carb with little work and good performance?

I ran 11.90s with a sort of similar combo and a 670 street avenger. I think that 770 is a good choice.

My heads are maybe bigger than yours, and I had an RPM Air gap, so who knows if this helps:

Initially I had a bad stumble when cruising and then matting it.

I went with a 35 squirter and the orange pump cam on hole #2. It had very good driveability, and smooth acceleration either footbraking or on the transbrake. I used the second to softest spring. Can't remember what color that is.

For the average weather conditions around here (about 2100 feet DA) mine liked being jetted up 2 sizes from stock, but again, that was a 670.
