To all:

can someone confirm absolutely, what distributor gear material is correct for a 1990 2-3 dual plug (Efi) engine?
I procured a NOS 1977 to 1982 Mitsubishi\Ford mag pickup distributor and it has a cast iron gear.

I will be retrofitting it with a home brew backbiased Hall effect trigger and a 24-2 wheel to act as a rudimentary crank sensor to trigger a micro squirt for spark control. Since the lower EFI intake won’t allow a full height distributor, a gutted body with a flat top cap to protect from debris will be created. The distributor body minus cap and rotor should clear easily. Only 3 wires enter from bottom of dizzy.

this will be a well documented project with video.

eFI manifold will be adapted for an Edelbrock early 600 cfm four barrel and linkage for secondaries will likely be altered for timing.

if carb proves to be a tiny bit too big, and even if not, I’ll be building an adaptor for a Weber 32/36 progressive as well. Project is not a hot rod project, it’s a future proof failure proof, roadside repairable downgrade to the 1990 truck.

so I really need some insight into the 2-3 distributor as aside from the part I have in hand, I’ve never seen or touched the distributor drive system for a 2-3.

looking for insight into some intermediate shaft it has??? Please throw me a bone…

This on the coattails of nearly 100% success of doing a similar action to my 2001 Explorer 5.0, now running pertronix igniter II, edelbrock carb, and maintaining full electronic function of every other faculty of the car. Out of the overall simplicity of the ranger and uncomplicated systems (mostly, no luxury stuff to support!), the ranger conversion should be ,inch easier. The distributor hybrid is to avoid cobbling a real crank trigger together from later model car parts. Forsake the vane trigger and just sidecar a short distributor.

thank in advance for the help and insight. I know others have desired to make this conversion and due to fitment issues it is a PITA/impossible. I intend to succeed and prepare a path for others to do so simply.

see ya
 
I've heard before but don't remember but I "think" you can pull the gear off the oil pump drive and just use that...
 
Scott, the oil pumps rive you refer to is the dummy shaft, correct?

What is an intermediate shaft? I have seen the term in regards to the 2.3. Is there more shaft (different from a normal v8) below the distributor on a 2.3?

Anyone have a shop manual picture they would screenshot of the exploded view?
 
Yes, the dummy where the distributor would be

The shaft that drives the distributor in the Lima world is I believe called the auxiliary shaft, it's been a bit but there's a oil pump drive between the distributor and oil pump like there is in the V8's, don't know how they compare though...
