Brad,
I would not trust the timing marks on the sprockets. My understanding is
the best way to "degree a cam" is with a degree wheel & a dial
indicator. Check out this link,
http://www.ridgenet.net/~biesiade/camdegree.htm
<http://www.ridgenet.net/%7Ebiesiade/camdegree.htm> .
or http://www.webcamshafts.com/cam_glossary.html both explain the
importance of doing this right. I'm in the same boat & will be trying my
hand in the next few weeks. If you finish first I'd like to hear your
results. Besides these links the book Engine Builders by Tom Monroe
gives a very clear explanation & understanding of how this is done.
