Michael,
     You might consider an ignition system such as the one posted here
some time back by Lynn Hanover........It consisted of modified 80's
model Chrysler/Dodge V8 distributer pickup coils (2) mounted 180
degrees apart around a single reluctor in an aluminum disc bolted to
the front pulley and triggered by two Chrysler ignition units from the
same model years.........I do not have the Lynn's wiring schematic for
this on my computer so maybe Lynn will jump in here and post it
again.........

Michael,
     You mentioned a distributor.......Are you to be carburated and use
an early point type or electronic dist. which are very tall ?..........The
waterpump/thermostat housing can be shortened and the alternator
relocated to the side leaving the stock waterpump in place.........If
you use Tracys EC2 the tall dist. is eliminated and replaced with the
short 86-91 ignition POS (position sensor)..........FWIW
