I swapped out my Edelbrock 1407 carb for a Quick Fuel Q750 a few years ago. The change was dramatic and although I knew that it was running very rich, I had never bothered using the AEM Wideband to tune it.

Recently I drove to both Mopar Nationals and Moparty. On the way to the Nats, I knocked out an astounding 12.2 mpg. After a gear change I got up to 14.2 on the trip to Moparty.

Something needed to be done.
