Let's talk. I thought = reluctor was the part that fit the distributor shaft
with the 4 or = 6 tips to be picked up by the pick up coils. Are the pick up
coils = not what we want to mount and just stick a couple of magnets 180 =
degrees apart on flexplate; or, do we need to do as Bill says and = get a four
cylinder reluctor, grind off every other tip and set = the 102 and the 103
pick ups 180 degrees apart and run them to = separate rotor plug pairs?
jofarr, soddy = tn


A reluctor is = anything use to upset the flux field around the coil on the pickup coil. = The Chrysler style pickups are biased by a built in magnet. So the = reluctor need not be magnetized in order to work.

If you use a distributor you can mechanically distribute the = trailing ignition which is required.
=A0
Or, =
=A0
For crank triggered:
=A0
=
If you fire both leading and trailing in each housing at the same = time, then you need two pickups 180 apart, but only one reluctor. The = reluctor can be a=A0steel pin sticking out of a disc. Or a screw = sticking out of a front pulley. One pickup fires both plugs in the front = housing, and the other pickup fires both plugs in the rear housing. You = use double ended coils, or two coils, one for each plug, if you = like.
=A0
This avoids the need to distribute the = trailing ignition with some other mechanism.
=A0

I used an early front pulley with the 4 bolt holes. I built a thick = aluminum disc. At the edge of the disc I drilled a hole a bit smaller = than a 10 penny nail. I drove the nail through the disc and trimmed off = the excess. I reduced the diameter of the disc until about 1/3 of the = nail as exposed.=A02 pickups one reluctor. The pickups can drive a MSD = or a Chrysler amplifier.
(you would need two).

=A0
This works so well it is amazing. Put a timing light = on it and it looks like the engine is not running.
=A0
=
I added a Mr Gasket degree wheel over the disc for timing = adjustments. Very nice=A0piece I must say. =A0My camera bought the farm = last night. If I can find that crank pulley I will publish a picture, = with a new camera.
