Webers look awesome but they are a brass-plated-b!tch to keep in tune... The slightest bit of dirt in an emulsion tube will give you a carb that sputters, burps, backfires and generally runs like cr@p.
Now that iI've given you the bad news - The throttle response is pretty good, but not as good as a single 4bbl that is setup right. These carbs are meant for mid-range to top-end and really don't like low RPM use. When tuned right they are sweet as you can find. When in the proper RPM range, they will pull you off a corner like nothing else short of a good EFI system as they are darned near immune to cornering forces..
