I recently removed the 2bbl from my son's car and replaced it with a rebuilt edelbrock 1406. (Chevy 350/350) I also tuned and tweaked my timing. The MPG improved dramatically. I can get 21+ mpg on the highway now in a big heavy mid '70's Monte Carlo. With your tranny, gears, and tall tires, you will probably be able to get considerably better than that. I am inclined to believe that my timing adjustments did more for my gas mileage than the carb swap. Dig around on this forum for the "HEI Recurve" post. Some here said B.S. to my results, but that happens from time to time.
BTW: I totally agree with Tech on the Quadrajet, I used the edelbrock because the intake I had was a square bore. A QJ would have been my first choice.Last edited by 65ny; 06-04-2008 at 06:47 AM.

Visited a family member at Dockery Ford from the time I was 1 year old through their ownership and then ownership change to Morristown Ford. Dockery was a major player in the Hi Performance...
