Timing belt ?

[RICHARD KROL]

Another solution for the non-rotating crank pulley.  Was the engine in question viewed at night under a light source that was most likely 60Hz.  The rotation speed of the crank pulley could have been in sync with the 60Hz. giving the appearance of no rotation?  If he was using a flashlight this theory falls apart.

  Actually, it runs off the cam.  It goes into the head.  On the I-5, anyway.

  You could run the dizzy off the crankshaft, but then there'd be a wasted 
  spark at TDC on the exhaust stroke.  And coil charging time would be 
  halved...
