Degreeing Cam?
Hey guys
I can't reach Comp Cams until Monday but this is my question.
I have gone through all the degreeing stuff, several times, and keep coming up with an intake centerline of 107, cam sheet states 106. Do I need to be concerned over this? I have a 9 key crank sprocket, can I move it one keyway in the retarded or advenced direction and accomplish anything? I set the sprockets up with both at TDC originally. The keyways are marked at 2 degree increments, that is 2A, 4A, 6A etc. but I don't know if that would be a linear function in moving 2 degrees and centerline moves 2 degrees. NO experience with this so just curious as to what you all think. Thoughts?
Thanks
George

Thanks Scouder
Actually Played with it a bit and with the crank sprocket on the 2A keyway I get 106 to 106.5. Also the valve open/close are close then they were. I was as much as 7 or 8 degrees off on each. Now I am a couple of degrees off which I'm thinking could be that I dont have the indicator tip exactly parallel with the lifter path. Close as I am going to get it anyway. Tried various keyways and this was the closest so away I go. Thanks again
