Just got my car running again. All original '67 with a 283. At 116,000 original miles, it has never been rebuilt. Runs well; just converted from points to HEI and the compression is mid 150s across all cylinders. Any clue to gas mileage range is appreciated. THanks.

No idea, you'll at least need to mention what transmission and final drive ratio it has.
