cam advance & timing

[0X01B8]

hypothetical question.  let's say you have two identical motors but one with the cam advanced 4*.  would you expect the advanced motor to want more, less, or the same initial timing than the other?  thanks.

slightly more initial timing, but less than 4* for certain.
advancing a cam does many many things, but one of the main things it does is shift the entire powerband backwards down the RPM scale.
