    Looks and sounds good on paper but from what I measure (I rolled the engine over 4 revolutions and measured 4 times and got the same numbers) that is incorrect. In the real world physical measurment it comes out nearly double that.

    Correct...that adjustment can be measured in cam degrees. That meathod will produce a number in cam degrees.

    Every DOHC sprocket I've seen has 38 Male teeth.

    That would 9.47 degrees between teeth. About 19degrees when referencing crank rotation.

    And now that's where you have me confused. I get the math.... but by the way you degree a camshaft it's by degrees of crank soooo the math I have on how much my camshaft is advanced/retarded is incorrect of actual cam degrees changed and only half of what I'm getting?
