Stock 350/350 combo (mild RV Cam), 4BBL Qjet, 3.07 rearend with 275 /60 R15 - I haven't seen 10mpg yet, one time I got close.

Though I barely have over 800 miles on the rebuild and I do have a Qjet sent off for rebuilding and tuning. I also have set in the garage / driveway with a lot of idling or very short trips for test runs and not going easy on the gas pedal. Only a few weeks ago did I figure out I needed to adjust the kick down cable for the TH350. Before that, WOT did not much of anything.
