Well if I have to admit ---
386 mph in a 1970 Dodge Dart with the Deacon's and Mayor's daughters in the back seat getting ready for the date..........
It was difficult to keep my eye on the old back country curvy hilly road, the speedometer (which had recently been calibrated to 295) and the rear view mirror watching the young ladies get ready.
If I remember that Dart had a good straight 6 with about 50,000 miles.
