I did this swap on my 95 Ex. Here's the deal:
You will have a check engine light for the missing cam sync. I have a solution, I just haven't finished it yet.
I took an OHV cam sync, took it apart, and cut it down in my lathe.
Then I took the SOHC oil pump drive, dissassbled that, and cut it down on the lathe.
I pressed the 2 housings together.
I still need to weld them together, assemble it, and install it (hope it fits).
(There are a few different cam syncs and oil pump drives over the years... You have to find the right2 to make it fit the block and work properly.)
Now, with no cam sync, it will run. BUT, you will be running batch fire, instead of SEFI. Your idle will be a little rough and you'll have a little less power.
Speaking of power... How much different do you think the sohc will be??? Don't expect too much, your running an engine on the wrong programming.
What are your plans for the 24lb injectors? Do you plan on swapping them out for 19lb to match your programming? Or find a mass air that will work with your computer and is calibrated for 24 lb injectors? Now 24lb injectors will work in place of 19lbers, but the poor atomization will cause a lose of power.
I hope you know you will have to loose the knock sensor on the SOHC... And with its higher compression, you will have to run premium fuel from now on to keep it from knocking.
There's some other stuff that I'm forgetting, but I'm going to pull that engine and trans to do timing chains and a 5spd swap. If I remember anything else, I'll add it in here.
By the time you add up all the little power loses from all the little compromises, you'll barely be making any more power then the OHV you replaced... And now you'll have those timing chains to worry about. (I don't care what anyone says, Ford never fixed the poor design, they threw band aids at it to get it through the warranty period.)
