I know its been a couple years since this thread was started but I still have a some questions concerning the fuel economy.
I've had an electronic ignition installed with a complete tune up and a new Edelbrock carb; would these upgrades improve the fuel economy? I'm asking because since the new upgrades and some much needed attention to the engine, it appears that its running a whole lot better than it ever has since I've owned it. Before, I could not drive at least 100 miles on a full tank, which maybe last about a couple days. Now its nearly an entire week of driving before refueling.
Some info on the electronic ignition would be helpful.
Also, what is the fuel capacity or gas tank size for my vehicle? I've checked Google and nothing. AutoZone is showing a 22 gallon tank; is that correct?
