How's it going everyone. Just have a quick question. I searched but didn't find an answer that I was satified with, so I'm asking..sorry if this is ot. I have skunk 2 cam gears on my LS and I have a couple of questions. First...each mark on the skunk 2 cam gears is equal to two degrees of cam adjustment, right? Secondly, If I adjust make intake cam to +1, what do I have to do with the ignition timing to compensate? Thanks a bunch guys. My bad if you guys are sick of hearing this topic. Thanks again.

 

every time you change the intake cam, it changes where the TDC sensor is relative to the cam timing. you MUST reset the timing. Dont touch the dist until you have the advance or retard that you want relative to where you are adjusting cam timing. the ignition timing doesnt track with the cam, however when you do move the cam, the timing will move in a 1:1 relationship. +2 on the cam gear is +4, -2 on the cam gear is -4 you have successfully adjusted 8 more degrees of separation into your cams and more than likely have tagged a valve. they can not only hit pistons, but each other.

once you adjust the gear you must adjust the timing. if for instance you had 16, which is factory timing then went to +2 on your +5/-5 gear you have advanced the timing 4 degrees. you now need to clock the ignition timing back to 16-18degrees. if you run your car with too much timing advance you can prematurely wear rod bearings. not to mention run un-necessarily high cylinder pressures.

 

Thank you very much for your explanation....
