Although I'm sure there quite a few domestics in GA that can beat Clark, they have yet to show themselves (some of them don't even have internet access, but have owned 9 second cars since the mid-90's)
The only competition that I'd bet against Clark would be Eddie Bello (from New York)......and I haven't seen him since the Nopi Nationals back in 1997 @ Commerce, where he ran a 10.02 @ 154 in his 911 and that was with a slow ass launch (he didn't have his wheelie bars installed on the car at that time, so he couldn't do a hard launch). Later that year or early the next year (if I remember correctly) I think he ran a 8.9 @ 172.
Lately I've heard he has another 911 with even more power...........
