Heads up
I have a 89 with the 4v intake manifold and I'd like to use it on my 91 with efi.
Are the heads the same? Will this manifold bolt to these heads?
I hate the efi in my 91, You can't hardly work in the engine bay. Plus my lower efi intake is damaged.
So I figured I can do a carb conversion instead of repairing the efi lower.
Then I would have room to work in there.
I need to know about the transmission.
What issues will I have.
I have the e4od in both vans but I'm sure there is something different between the two.
Thanks

You'll do better replacing the EFI lower with a good part. Carbing it is going to get messy. The E4OD needs the computer to run it. Then there's sorting out all the wiring to see what needs to be there and what doesn't to run a carb. You'll also need a different fuel pump to feed a carb. The EFI pump puts out too much pressure and volume for a carb setup. You'd need to run a regulator and hook up the return line to it.

'89 was fuel injected. What motor do you have? I second replacing the lower intake. There are stand-alone units for the e4od but your talking quite a bit more money with the fuel pressure and wiring issues then just a lower intake. Plus you'll need to buy a carburator/intake. Also a good running efi will be smoother than most any carb in varying conditions.

Moroso (spelling) makes a fuel log that uses your return line to drop down the pressure greatly.. I ran a carbed 351w with the fuel pump from my 4cylinder motor in my '87 mustang. Worked okay as long as you didn't try to turn 6 grand on the 351w. Worked good and didn't have to drop the tank.

The 89 has a 351w Ho in it. It runs great and I like it much better than the efi.
Plenty of room to work on and seems to be more responsive then the efi.
I also like the fact that I'm removing a lot of electronics that are getting more scarce to find.
I researched the distributor from Msi and there control module for the tranny.
I'm on the fence about using the intake off the 89 and buying a new carb.
Not building a hotrod but just a good running engine that's easy to work on. Old school.
I have thought about using a intake like the elderbrock performer but don't want to overload the cam.
If the heads are the same then I'm good to go but need to know first before I pull the green light.
Thanks guys I do appreciate the help

NOT SURE WHY YOU CAN'T FIND ELECTRONICS. THE SENSORS ARE AVAILABLE EVERYWHERE.

THIS MAKES NO SENSE EITHER. HOW ARE YOU GOING TO OVERLOAD THE CAM ?

I'll be running in the lower range so a dual plane intake will be better for me.
What type of problems did you have on the ranger swap?

Calvin you will open a massive can of worms if you put a carb on that motor, the E4OD will not work without the computer and it needs some of the engine sensors like the MAP and TPS to operate correctly.

Okay was wondering because I had an '88 and it was efi. Why not grab the transmission from the donor van too if its there. For the amount of work your looking at you will get very little if any gains going from efi to carb unless your going to ramp up the power a bit. Not sure if the Aod had any controls on it from the computer. If you want more power you could just step up your efi a little with a computer friendly cam and steeper rear-end gears. Check out some Mustang forums for some ideas. The 460 forum is full of tuning the SD-fi enough to not mess up the computer. The 351w isn't any different. You are limited but unless your really wanting to step up the power you'd be fine with the EFI.

Which I need because I tow a 5000 pound camper and the shift points in the standard trans does not hold my gears long enough to keep from pulling the rpm down.
Basically the ecm I don't think after the swap will be doing anything as far as engine and trans control.

You're going to spend a pile of money and not see any performance improvements. The 351HO has a bigger cam in it that is why it feels more responsive, so that is what you should do to the '91 and then grab another lower intake from the junkyard and put it back together. All the smog junk can go away, the only thing that should remain is the EGR tube at the front passenger side, that will clean up the engine bay a lot. The cam to use is the Crane 444232.
