For whatever the information is worth, I had driven my 56 Caribbean about 6000 miles with conventional stock ignition and about the same # of miles after putting in Pertronix. Gas mileage did not change as a result, about 14.4 or so at Interstate speeds. This probably relates to about 16 mpg or close to it on pre-ethanol gasoline.
