What's so bad about 11 in town, your right in the normal range as far as I know. I used to have a 305 and that's about all it got no matter now much I toyed with the carb. It would get about 16 maybe 17 on the road. You might try going a couple sizes smaller on main jets to see if that helps but it just takes so much gas to run them no matter what you do. You probably have the same trouble I had, to high of gearing.
