In the vent your heads start to hurt just stop reading this. My first crank trigger system that worked real well was one reluctor on a disc on the front of the crank pulley. Two pickups 180 degrees apart. Each driving one Chrysler amplifier ($15.00) and each amplifier drivng an Oldsmobile double ended coil, with one wire to each plug on the same housing. So, each system ran two plugs in one housing. Lynn E. Hanover. -------------------------------1134674613 Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable
