Well I didn't attend, but here are some vids that the other GTO guys (yeah I know but they have the vids, so...) got with some Camaros:
http://videos.streetfire.net/video/FCF7926A-6DDA-4120-8B57-CBE0F3D96661.htm (actually it looks like a 2nd gen to me, but I can't really tell)
http://videos.streetfire.net/video/D40FAC62-6BE2-49DA-9A44-422C2FBC9B98.htm is supposedly a blown 383 IROC, but it looks a little slow to be blown, maybe N/A
http://videos.streetfire.net/video/DB9CBC0C-50FE-4C78-87A3-01914AD90D34.htm is a procharged LT1 Camaro
http://videos.streetfire.net/video/D9295E34-B698-4FF4-AD5D-3E4FD337E6E8.htm against one hell of a 2nd gen
and last but not least, one bad ass pickup: http://videos.streetfire.net/video/7FE34E8B-096C-4A63-9B6C-A1552D34DB7B.htm

Anyway, hope you like them. I know a lot of the times filmed are of GTOs but the guy filming is a friend of one of the GTO drivers. Oh and BTW, the times may seem like they suck, but it's only because the elevation is approximately 5000ft.
