I live in Belgium, but actually my cars in France. So I can't work on them for the moment (I have money problems too, ha ha) . My better result with de 1975 Fury is for the moment something not far from 28 mpg (8.4L/100km) at a steep 62 mph on highway, without mods, with the original holley 1945.
Mmmmm, need to sleep, again.
