Which Carb Gives a Balance of Power & MPG?

i lost track i dont even know if thats the same intake he was pushing, but that was the first thing that popped up and it is a pretty informative shootout and nice that its a b motor test so it uses the exact manifolds i would be using. i was planning on running the 666 383 iron intake i have with a 750 VS on this 400 but i really want to try a thermoquad. this car isnt going to be hitting the strip to often. i built the dart for that.
