Bummer, I regularly cruise on the freeway in my Duster at 80-90 mph. Might be time for you to rebuild the front end, get the alignment better and put in some stiffer t-bars. That's what I did anyway. With 2.94 gears I've had it over 110 several times and it feels the same as at 90 or 75... like it's glued to the road.
If I somehow made a ton of money I'd LOVE to build a restomod wing car and do 1/2-mile and standing mile drags. Keep in mind the drag coefficient of a Daytona is only 0.29 which is still lower than most modern cars. Yes they need to be lowered and the suspension stiffened up to handle high speeds but the potential is there. I need to watch that video on the #71 car again but weren't they able to hit like 230 mph with it on the salt flats? And that engine had to be making 700-800 HP at most...
