I still don't know how the Ford system works!  (BTW, MSD sells a
crank pick up ignition system now!)  But, if you set the crank
pickup to give pulses at some standard, nominal crank angle, like
10 deg BTDC, you could use the pickup pulses to fire your engine
and then throw in the required time / angle offset to get the
desired firing angle.  Of course, the time required to get a desired
crank angle offset from the base pulse position varies with rpm.
