Dont even try to do the dot to dot... you will never
know what you have... degree it in... and if this is
a street car advance it more than the 108... 104 would
be better for the low end torque... even 102
EDIT
To the manu... 108 is straight up... all they do is
move the key way 4* from the 112


When you put the cam, gears , and chain in you need a starting point ( BEFORE YOU START DEGREEING IT IN ). Dot to dot is your starting point. Quite often, you will find ( WHEN YOU START DEGREEING IT IN ), that you will be on the cam spec numbers - or very close. You can make your adjustments form there. As I said, this is a 4 degree advance web sight. I disagree with that approach for several reasons. 1. I'm not as smart as the cam designers. 2.I don't own a WEEGEE board. 3. If you did your home work correctly regarding choosing a cam, you shouldn't have to advance / retard it to make it work better. At least start with it in per the cam card. Then, if you are not happy with it, change it. If you run the motor in and get some compression readings it will be a good place to start. Then when you start moving the cam around, you can see how it might effect the compression readings. Generally, if they start to drop off, you went the wrong way ( or too far) advancing it. If you have to advance it 4-6 degrees for street use, you bought the wrong cam.



Theres only one problem doing it that way... being
a street car once its in and it runs... he will NEVER
move the cam to see if its better or not.. I have
never seen a guy change the C/L on a street car as
long as it ran(I am not talking about a racers street
car but the average street car guy)
