Tuning the carb and timing might add a bit, but generally trying to eek out a few more MPG on a 1 ton van is a search for minimal gains.
For now I think I've done all the tuning I can do, it's just a matter of going on a drive and putting it to the test... I'm just a little hesitant since the last time I drove it was when it broke on me on the freeway... I'm trying to make sure I've done everything I can to prevent another break down... Living where I do it's not like I can get towed home either. I'm about 4 miles off the freeway on a dirt road and tow companies generally don't drive out here!
