How about a Motion Cobra?

But really, by your standards EZNova - those standards being modern day tech and knowledge applied to an old factory-offered Musclecar (I think that's what you mean, if not, I don't know what you mean), then 1968 SS/AA NHRA Hemi Barracudas and Darts are the cars to beat - they're still running 8-second quarters today.

And my recollection is that Motion did not guarantee a 10-second time slip. It was 11s. This is from his "warranty" :

"We think so much of our Phase III Supercars that we guarantee they will turn at least 120 mph in 11.50 seconds or better with an M/P-approved driver on an AHRA or NHRA-sanctioned drag strip. Phase III Supercars are completely streetable, reliable machines that will run these times off the street."
