quickest et,s on an edelbrock carby

You can go fast with an eddy carb, however, you will be leaving power on the table. How much power really depends on the combo.

Walk around the pits at the drag strip and see what most of the faster cars are using for carburetors...I would be willing to bet you find more than 90% of folks using Holley style carbs, because they just make more power. Usually the only ones going fast with other carbs are only doing so because they are limited by what they can use for their race class (like stock classes).

So yes, you can go fast with an eddy carb...but you could probably go faster with a well prepped Holley.
