as you can see in my sig. I have added mods since the last time I had it at the track, also I ran a 98-99 SS 6spd at the track and he was only running 13.9-14.1@101 with little spinning off the line, so maybe some are just stronger than ever, Heck look at GM TPI I have seen stock one run anywhere from 14.6-15.8's! So maybe LS1 cars are the same, I have never seen a LS1 car run better than 13.6's but with all the claims of low 13's I could believe that with a good driver and a strong LS1 car that low 13's are possible.
I am thinking of going with the mac, but I am not sure EZridn as you can note that I am looking at cold air induction so look for a killer NA motor in my future either 331 or 347 and maybe some stage 2 Trick flows.
