Around town get 10mpg, but highway cruising 18-20mpg. GT40 with Roush 427SR, 3.77 diff and .64 top gear. Maybe I've got an aerodynamic advantage over you Cobra guys? Leaned carb out a lot with A/F meter. Off the shelf carbs have rich idle restrictors. You're pretty much on the idle circuit under 2000 rpm.
