I have a gentleman over on speed talk tell me to use .020 to center the cam with asymmetrical lobes. I am still trying to figure duration at .200 lobe lift. Do I read the wheel for this or is it a math equation? Spec is 190 lobe lift at .200.


Isnt your cam installed 2 degrees retarded? If so, the @.050 numbers line up close enough. Lifter bore bank angle and plane errors can move the @.050 numbers around quite a bit.

Send it.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
