help with degreeing my cam

[scherp69]

I thought I'd start a new thread just so people will realize it's a new question. I've spent he past hour or so trying to figure out how to degree my cam. I have both heads off and am using this method: http://xtremecarzone.com.au/index.php?showtopic=805 It's posted a few times online, this was the easiest layout that I could find. It's just Car Crafts article on how to do it. I've gotten to the point where it says:

Comp Cams recommends checking cam position using the intake centerline method, which is pretty simple. First rotate the engine until the dial indicator reaches maximum lift and then zero the indicator. Turn the engine counterclockwise until the indicator reads 60 to 70 degrees on the opening side of the lobe. Now rotate the engine clockwise until the indicator reads 0.050 inch before max lift.

I'm don't understand why I need to turn it so the indicator reads 60-70 degrees.

I don't know if I was doing it right or not, but I was basically taking the readings on the wheel at .05 degrees on either side of max lift. The first time I did it, it gave me readings of 68 and 151 so a total of 219. When I divided by two, it gave me 109.5. My cam specs read 112 intake centre line. So does that mean that I have to move my crank two notches over then??? I'm so confused right now. What ever I do, I'm going to leave it until next week now as back to work in the am. In the meantime, any advice would be greatly appreciated. Thanks in advance.
