When you run multiple carbs like side draft Webers, it does smooth out your idle & helps throttle response.For like when you have bigger cams. Also for camshafts, you can get away with[generally speaking]10 more degrees of duration as compared to a hydraulic cam.Example 220 hyd as to 230 duration for a solid.
Webers makes your car a better street car & is also great for drag racing.
