I never ran it stock or even close to stock. I rarely go to the track, my first pass down the track was a 12.2, that was with a blower. I ended up doing 11.9 and that was only with 365rwp, when it was all said and done I was doing 394rwp and 440rwp with a 50 shot. And that was still with stock heads and cam, I figure it would have did 11.4's or better if I had taken it down the track.
