Been working on the interior lately and will probably be doing the engine pretty soon. Runs fine but it could use a freshing up.
Probably going to change the trans to an E4OD for the overdrive as this this sucks gas and really revs out on the freeway.
I have a E4OD wiring harness and the ECU form a 91 F150 so I can keep the SD injection, and control the trans with all stock ford parts.
I'll find a new photo hosting site at some point and post some pics to show off.
I'm about to do the same swap, I'd like to see your pics.

I'm also going from 91 351/c6 to a 89 351/e4od, I liked over the schematics, looks very plug and play.

I wouldn't call it plug and play but so long as you are competent doing wiring it's not too bad.
You will need to write your own complete pin out of the ECU and you may run into some differences in the emissions equipment between model years that you will.have to address to get the idiot lights off.

Hmm, I hadn't thought of sd/mass, I'm pretty sure both of mine are sd, 89 and 91, I didn't think trucks got mass until 96 or 97 and it was an odd cali thing

Cool rig btw!

I had posted this on another forum.
The one thing I can say is to go through both pin outs and check each circuit one by one for different equipment.

We'll, I got around to getting the transmission in. Haven' touched the motor yet.
The E4OD over drive really helped out. Getting 11 mpg at 65 mpg. Might be a bit to be had just yet as the tires are a bit low and the idiot light is on for some emissions codes.
I had to use the computer from a 91 F150 with SD to get the transmission to run and the 91 has a canister purge valve where the 88 doesn't. Lucky for me I have the parts from my pile to address this. Just need to install it and clear the codes again.
I was more focused on getting the transmission sorted out and running. Now that is done I'll fix the other little stuff and see what happens.
I'm really impressed with the C6 to E4OD swap though. Shifts a little soft but the timing/load is spot on. No hunting between gears or undesirable behavior.
Not an easy swap though... I had to a lot of harness surgery to make it work which requires writing my own schematic and pin out as ford changed the color code in 90 or 91.
I used the transmissin harness from a 93 F150 that I took apart at the ecu plug, the OD cancel switch, etc... I ended up ordering a bunch of ecu pins and some custom striped wire to pull it off. It turned out really well, its all factory quality wire with no indications that it didn't leave the factory that way.
The linkage was a bit of a pain too but as the two use different systems but I was able to figure out the right travel ratios in the linkage to make it play nice. The tough part is that the C6 and E4OD have different gear location through the sweep. It' the degrees between the gears that is slightl different but the total sweep is the same. So, the solution was to alter the linkage at both ends of the shift rod to build in an exponital. In a nut shell, the first bit of sweep between park, neutral and drive moves the selector fewer degrees than at the far end where drive, second and first are which it moves more.
If you've ever played with model airplanes You'll know what I'm talking about with mechanical exponital. Electronic is just soon much easier...
Anyway, it's not a weekend swap but in my application it's totally worth it.
I'll probably start building a new engine in a few months. Expensive and slow going but I'm pretty sure that it' going to be a fun project.

And...


I just did a 88 351 C6 to E4OD. This is not an easy swap...
Mechanically its not too bad but the linkage is completely different and I had to make some linkage hardware, not too tough if you can do fab work. The C6 has a shift Rob, the E4OD was cable actuated.
It's the electronic parts... I took a computer from a 91 F150, the transmission from a 96 Bronco and then most of the harness from a 93? (I forgot...might have been a 94) F150. Did a complete pin out for the two and repinned my original plug with all the stuff for the E4OD harness. Had to get some custom printed wire (color and stripe) and make a few splices on the original harness.
For the most part it was pretty straight forward but I did have to add a canister*purge*valve*to satisfy the Check engine light... my 88 didn't have one, although that plug did exsist in my original harness, the computer wasn' looking for it. Not so with the later computer and it actually has to sense the coil in the valve as a dummy plug wouldn't work either.
I believe the 460 version is nearly the same as far as wiring to the factory computer. Get both pin outs and go through them both, you may get lucky as well. All of the different ECC pins used by the E4OD wherent occpied on the original ECC in my case. You will have to very, very carefully trim out the blue plastic plug plate that goes to the ECC plug unless you want to swap that too, which would require a complete disassembly of the ECC plug.
Good luck! It's totally worth it and doable with nothing but factory parts.

And.... so with the C6 I averaged 8mpg.


Well, trans is sorted... sorta... tires aired up I got 11-12 mpg between sacramento, CA and Camp Verde, AZ.*
There be some pretty good hills between the two. It's safe to say, needs more torque.*
A little more punch at 1800 RPM and it'll pull those hills without downshifting out of the overdrive.
I have a little front torque convertor seal leak so i have to pull that SOB yet again. And I'm gonna put the shift kit in. The slip between gears while climbing really heats the trans up fast. Other then that I'm really pleased with the E4OD. The ratios are spot on for my set up.

Sweet! So did you provide the rear diff or not? What gearing did you go with? I have the same van ('90 Fiesta) but have the E40D already. Would like to see if Agile will do the same for me. They had no issue doing just the front end fab work for you? The wheel pattern is the same on the 50 TTB and the van right? 8x6.5, so you could have left the old rims on it for you trip to SD? How much cross member mod does it take to clear with the TTB? Did you clock your t-case for more clearance?

Oh, BTW. There is a google chrome patch that allows seeing photobucket photos, at least for now..

Thanks for sharing. Awesome!

Levi, that is a cool rig, after enjoying my first Van (2wd) I have been trying to convince my Wife we need a 4x4 adventure van, since you got the ttb for 500 I think I might have a chance now. How did the motor turn out ?
