umm yeah, ran a fricken 14.20 at 97.xx mph. with a 2.16 60 ft time. But have raced two stock LS1's and beat them by about 2 cars. So, everyone thinks it is the cam timing... the ignition timing wouldn't do much?
well, here it is... I took my old harmonic dampner off and put on the new one. When I put the new one on, I found that the timing (w/spout out) is at 18*... so I back it down to 15* and get a little bit of power, hardly noticeable. I don't know what to do now, do I have to degree the cam?
just a quick thought...when you checked your timing, did you pull out the spout connector? If not, your 15* timing may really only be around 0*, therefor being retarded.
