Is a Holley 750 DP too much carb?

The double pumper carbs will launch a car very hard if it matches the rest of the set up, but it was not designed for the street, will it work absolutely,but if fuel mileage is of any concern there are better choices. TQ or holley avenger line would be two I would take a good look at .I have a very nice 750 dbl pumper on my bench it is a power house on my 340 with a 242 at 50 cam and 391buted 4speed m1 single plane ported procomp heads...but my 850 TQ is on my motor 90% of the time not much differences in power but about 5miles to the gallon better mileage for just tearing around . have fun!
