3.9 V6 electronic ignition conversion
Mopar used to offer a kit to do this, but apparently it's no longer available. To swap a 3.9 V6 from the hall effect distributor to 80's electronic ignition, you will need an electronic smallblock V8 distributor as well as a reluctor wheel from a slant 6 distributor. Pop the reluctor wheel off of the smallblock V8 distributor and replace it with the slant 6 reluctor wheel. All of the other V8 internal components remain as they are. That's it. You use the V6 or slant 6 cap and rotor (same p/n). You will have to play with the position of the distributor (like when you adjust the timing) to get it to line up with the cap contacts. You'll of course have to wire the vehicle for electronic ignition, but that's a whole different post that I am sure has been discussed before.
This allows the use of the perfectly good 3.9 in other vehicles if you don't want all of the eccess wiring, computers etc. I did a body swap with a 1987 Dakota chassis and 1953 Dodge pickup and did not want a computer. The 1987 was the only carbed Dakota so look for an 87 intake, or else you will have to make a carb adapter or machine an 87 or later or find an aftermarket V6 4 barrel intake. Mopar made them as well, but good luck finding one. I'm not sure what you would do to make a Magnum intake work. If you could adapt a carb to it and plug up the injector holes, would it act like a tunnel ram? Hmmm.

All I know for sure is that my project runs like a top with this setup. And using one of the PATC overdrive wiring kits, the overdrive kicks on and off as it should. So I basically have a 1953 Dodge Dakota!!

3.9 v6
moe7404, u lost me. You're saying the tabs on the reluctor wheel aren't evenly spaced? Hmm. I have an extra one. I'll have to check that. It seems it would not run well then. You'd think it would shake all over the place. At idle it purrs and you have to be right next to the front of the truck to tell its even running.

go check the crank pin indexing on the Dodge V6 3.9. Dodge made the crank pins, that would other wise be on the same crank pin, splayed the get it closer to even fire. but is still a little off. the even fire GM V6 broke cranks cause they splayed the crank pins to far.
