I would recomend you get a good EFI set up. I tuned carbs for years (for power) and it is so hard to get them right. Most end up overly rich because it will run ok in most situations that way. It is so hard to get a carb right, and then the temps drop/rise 20 degrees and you are wasting fuel or not running right if you were running corectly to start with. I have a 1988 Mustang GT with a 302 mass air flow EFI motor. We routinely got 17 mpg city and 24 mpg highway with no thought at all about getting better mpg. That's with a non lock up torque converter and quite a bit of idling to keep the baby asleep. Boy that V8 makes babys sleep good
