BUT, your car actually ran 12.66 @ 3400 lbs at a strong 110 mph which is more like 330 WHP in my opinion (and according to most drag calculators like quarter jr).

So, I think it ran better than expected at the track! Maybe it had a really good driver mod?

Have you dyno'd it since adding the cams, port work, headers, 3" intake etc..?

Should really haul now..
