What's your favorite carb, why?

Holley's are my favorite and am presently running a 650 DP with a Quick Fuel base. That base is a stunning piece of machine work.

I like Holleys because I know them and they are what I'm comfortable with. I'd try out a Quick Fuel as they should pretty much the same as a Holley tuning-wise with the exception of some superb machine work.

Annular boosters are key to good driveability and allow you to get away with a larger than recommended carb. I believe that they atomize the fuel better (finer droplets) as well as pull fuel sooner.
