crank gear and the cam gear, as the chain stretches the cam gear is
retarded.  Whether this is enough to cause a change in engine performance is
debatable; however, don't forget that this will also retard the distributor,
a small amount of scatter can have a significant effect on performance.  The
higher the state of tune of the engine, the more noticeable the effect.
