Which Carb Gives a Balance of Power & MPG?

Car & Drivetrain: 1968 B/Cuda Convertible. 318 from 1985 5th Ave. Stock, possibly Stock +1 cam, 4spd manual trans w/ 3.23 Rear End. Dual Exhaust...generally, moderately Hot-Rodded.

Currently, I'm running a Road Demon 625cfm carb. I don't know my MPG yet, as the carb has only been on for about 20 miles or so. But the power is GrEat! I did have an older Holley 600cfm carb which gave so-so power, but incredible MPG.

LXguy "I'd stick with the carb you've got. You would have to drive a lot of miles and get a big difference in gas mileage to justify the expense."

I have to agree. I'd give your new carb a chance and dial it in before I got another.
