When you say 4' or 8' crank, you mean advanced or retarded 4 or 8 degrees with respect to the crank angle, right?

So if you advance your cam timing, you're moving your torque curve more into the low end, and if you retard it, more into the high end? Is that right, or do I have it backwards?

So stock cam timing for the Y8 is 0', then?
