Which Carb Gives a Balance of Power & MPG?

I definitely noticed better throttle response and torque when I swapped from an iron 4-bbl. intake to a Performer on my 318. And the one I have is non-EGR...

Sure you noticed a difference. you shed 30 pounds. LOL also i was speaking about the big block intake.you cannot find a performer without egr provision. they do not make one.
