Comp cams degreeing issue

matty wardle said

yeah this is what had me confused,dot to dot it went in at 102,so i moved the crank keyway sprocket to where it says 4 retard,re deegreeed it in and its now perfect at 106,i now understand that the 4 degree advance is the difference between lobe sep and intake centreline

It is confusing.
But dont forget, if you are using a Rollmaster set (I guess others are similar), when you use the "Advance or retard" 4/6/8 degree keyways...this is CRANK degrees not cam degrees.....so 4 degree on the crank gear is only 2 degrees at the cam (1/2 speed).
So I wonder about your above statement, just moving the crank gear 4 degrees, will only move the cam 2 degrees........ so how did you get 4 degree movement?

Are we confused yet?.....I am.....
Can the experts explain..
Do people use the "Mopar" degree wheel system or a generic wheel system..apparently the Mopar ones are different??
