Yes he did run 12.3. Everyone in the F-body club was at the track that day and my best friend is part of them. It would be nice if I was in the 11's but being the Z's are not good drag cars and no weight transfer my 60ft's are only 2.1. My best is a 12.5 @113. I am not sure what I will get until I run it closer to winter. Also, I ran a friend of mine with a LS1 that ran a 13.1 @109 on motor and now he has a 100 shot of NOS installed. I bet him real good. I am not saying that I am in the 11's but I don't think I am far from it.
