Yeah..they have.
Six speed, good air & a good driver (Evan Smith).
12.89 @ 109 for a 99 Z28 at Englishtown about 10 years ago.
It is the best documented example.
The fastest I've personally seen was 13.00 @109 by a friends '99 Z28 1SC(zero option 6 speed car)
I only went 13.5 @ 106 bone stock at Epping NH..My 1st time ever drag racing..
I started bolt ons shortly after.
Would love to back you up on that but he only went 108mph on that 12.89 pass...
