As stated before my 3500 pound wagon with overdrive gets 18.5 at 65/70. dropping 10 mph slower affects it little. Got same mileage 2 yrs ago on old 66 Chi to OkCity. Engine 277 V8 power pac fully rebuild including rebore 60 over and new pistons. I recall my 62 savoy 2 dr post with stick and 318, aftermarket duals, got around 16 but it was not on any freeways, all 2 laners. A pen pal in Ireland has 56 Dodge with 315 and 4 barrel, its all he can do to get 14 mpg and dont know if thats Imperial gallons or not. Lars |
