From what I've read so far, I guess I didn't really go all that far. Moved to Wisconsin from Ft. Worth, TX. About 1000 miles. Got my '49 going in April, '98, and made the move in August, '98. Loaded the ol' girl down and away I went. Didn't know if it would make the trip or not, but no problems. Did 65-70 all the way and still got 20-23 mpg with a 283 and TH350 trans. Of course 2.73 gears didn't hurt.
