After the carb rebuild, I think I've finally got all the vacuum leaks plugged and the timing adjusted as good as I'll probably get it. Ran to Pittsburgh an back pulling a small utility trailer, today to take some furniture out to my son's new apartment. 420 round trip mostly highway. The truck is running real smooth now and the trip average was 14.3 MPG. I ran mostly between 60-65 but the GPS said I got up to 75 at least once. The best I used to get was 10 MPG so I'm pleased with the improvement. I have a 350 w/ Q-Jet 4bbl and a TH350 trans. (no idea what the rear ratio is)
