I will retract my statement about the Dart/Barracuda SS not being able to run tens, but I will add the caveat that they were for track use only.
As per
this site.
The big news for '68 A-bodies was the Super Stock 426 Hemi package, available in the Dart and Barracuda. This was a drag race only package, featuring a race-tuned Hemi and a seriously lightened body. Acid-dipped doors, lexan in place of glass, factory delete of anything not essential to life on the dragstrip (e.g. back seat, sound deadener, window cranks). Lightweight van seats on aluminum brackets were used in place of the factory bench. They had a little sticker which indicated that the car was not for use on public highways, but for "supervised acceleration trials" only. It ran the quarter in the mid 10's in '68. Today, these cars dominate the top NHRA Super Stock classes (SS/A and SS/AA), and have broken into the eights! (Mopar Muscle Apr/94, Mopar Action Dec/93, Mopar Action Apr/94, Chrysler Power Mar/94).
