was wondering if the 91-93 mustangs with DIS ignition2.3 blocks can be converted to distributor,i know they have a sensorplug? where the distribitorhole is, was wondering if the auxiliary shaft has a gear to convert back to duraspark using a distributor,,have a chance to pick up on these blocks thanks

 

I believe so, but even if not, it's easy to change the aux. shaft. As long as the block itself has the hole machined for the dist. then it's doable.

 

The aux shaft has the gear on it. That piece that plugs the hole also has a gear on it and it drives the oil pump. There is no fuel pump lobe, so if you are planning on opening the fuel pump boss, you will need to get an earlier aux shaft.
Why would you want to go to a Duraspark and what are you planning for the extra 4 plugs?

 

thanks for the replies,i would use the duraspark but with an earlier 4 plug head, i have 3 efi mustangs right now but i wanted to mess with a carbed version with the carb adapter that bolts on to the efi intake,,just experimenting to make it simple,,there is a method running a 4 pin gm module with the duraspark distributor,suppose to give it a longer dwell with use of a the ford tfi ignition coil, will post later got to run

 

Yes, I've read about that. I have one of those GM mudules, been planning to put it on the Duraspark setup I have in my '68 F250, just haven't gotten around to it yet.

 

Use the TFI I module with the duraspark dist. It puts out a better signal to the coil. I've run both with E coils and earlier stock / aftermarket coils and the TFI I was more reliable. Both are easy to wire and give you the advantage of a centrifical curve vs the locked TFI IV in non computer set up.

 

thanks Rob! I did a search on using the efi original distributor and running carb, i found the wiring instructions at www.4m.net in the ministock tech section searching under "ford wiring" topic ,,,love the tough little ohc2.3!
