Debating a 4.0L SOHC/5.0L motor swap…input is appreciated

Well, I'll have to say that the 4.0 SOHC is actually amazing me! When I first started 'modding' the engine, I really didn't think it was going to do anything impressive. Now that I've done a few mods, all I can say is wow.

the SOHC conversion may be a bit cheaper since you are keeping your transmission.
But a SOHC or 5.0L into a Gen II truck are the same thing really, conversion wise if we are talking complete drivetrain, converting frmo a OHV to the SOHC or 5.0L is the same thing.

the alluring part of the SOHC conversion (save $$$ and time) is that it can be controlled with the OHV computer, and it can be had with a good 5 speed trans

My 5.0L fits better in my BII then Brett's SOHC fits in his 94, he had to notch his heater box more then I did and its touching. His acessories are also very close to the frame, I was able to get lots of cleaane all around.

Did I miss something in my conversion thread?
What else would you like to see?


If you guys are looking for a complete thread showing how easy it is to put a 5.0L drivetrain into a Gen II truck (IFS rack and pinion) I have seen a couple, including a really nice 97 Ranger that was running in a weekend, and a few others. You see its a pretty damn easy conversion since these trucks came with a 5.0L in them........it bolts in 100%
 






Jakee thats awesome the SOHC def responds to mods better then the OHV did, and the V8 does it too, since I went with a cam in this 96 its like a whole different truck.....

You have very good conversion/refurbish threads. The only difference between a typical explorer 5.0 swap and mine will be the custom shortened rear driveshaft I will need. lol I can't wait to get started, but I have to finish finals first. Darn school. It has been a year and a half since I started the project and now the motor is ready to drop in. Just out of curiosity, can an explorer 5.0 be started with open headers? Will it run without the 02 sensors connected? I just feel like pissing off the neighbors a little.
 






I am not sure if it will run, it should, I fired mine up with open headers, but not without manifolds

There's nothing better than firing up the engine after a rebuild. You'll be nervous and excited at the same time. I can remember my first rebuild. I turned if over and over and it wouldn't start. Had a friend double check me. he found one wire to the coil I forgot to hoop up. Told me to try again, so I try again not expecting anything to happen. When that sucker started my heart went thru my chest.

Anyways, I've highjacked this thread and I'm sorry. I have a bad habbit.
 






driving my 4.0L powetred BII for the first time was something, driving it with the V8 was awesome, but there have been a few times where it was not so easy, I remeber a 4.0L conversion we did into a 87 BII that wouldnt run, after all that work!
We checked and checked and confirmed firing order, fuel line routing, sensors, connectors, etc etc.
On the 4th day we realized that we did in fact have the fuel lines backward, not at th eengine but further back on the truck.
When that baby fired right up there was a BIG sigh of relief. Nothing is more nerve wrecking and exciting at the same time, as building a truck then getting ready to finally fire it up.....so far so good...

Your threads about your conversions in your Bronco and your X have much valuable information in them. I agree that if you are swapping the complete drivetrain that they are very similar.

I think your v8 conversion was a little more affordable than the average one. I want to keep my 4x4 when I do my motor swap. You went to AWD and then 4x4. I believe you did not need the AA adaptor because you went with the f-150 t-case which bolted up to the 4R70W right? I'm going to keep my recently rebuilt t-case. So not only will I save from keeping my current trans, but also I will not need the adaptor/F-150 t-case.
 






99sportx is getting ready to post up his v-8 swap into a sport writeup

it is very informative and well documented--and-he has the good v-6 driveline for sale---

I PMed 99sportx. I guess he has the OHV. It's unfortunate because he has only 46k on it and thats exactly the kinda motor I want for this swap.
 






Oh man my conversion was not on the cheaper side.
You can put a dana 20 or the 4406 F-150 case behind the 4r70w alot easier then getting the AA adapter ($600) and having the trans rebuilt to fit the output shaft ($800)
My radiator was $500, I bought my engine mounts instead of making them, I used the Canton billet oil filter adapter, I had driveshafts made, the big break I got was the free headers. Exhaust was $300+ it all adds up, tune up parts, etc,
I spent about $6500 and did 100% of the work myself (aside from trans and exhaust later)

It adds up so you have to spread it out over time!!

I have seen them done for 1/8 that cost, but then again I have also seen some seriously hack job 5.0L conversions, like with wire nuts on the harness and 100 extra wires still in place, hacked up engine mounts, notched frames, etc you name it its been done, from $500 to $50,000

if I was to do it again I would likely skip the transfer case adapter and build a dana 20 with low range gears, or go straight to the Atlas
The 1354 doubler would be great though now since I have the adapter.
The 4406 t case I put in my 96 is a *****IN case, it has a really low low it feels like and its really solid, but its also HUGE and barely fits inthe 4 door ex, it may not fit so easy in other trucks but its a great case behind the 5.0L explorer drivetrain
 






WOW 6500? I definately take back the whole cheaper than average comment.

So tell me about this adaptor you have...
 






the advance adapter for the ranger t case has been around for a long time.
It fits AOD and AOD-E automatic and converts the 6 bolt trans then to the 5 bolt ford t case pattern (BW 1350-54 Ranger trucks), you must remove the output shaft from the 4r70w (fancy name for a late model AOD-E) and replace it with the Ford AOD part (supplied from Advance Adapters. To install an output shaft in an automatic transmission the entire transmission must come apart as it is the first part to go in



Advance Adapters has a few different options for Ford t cases and transmissions, you should do some research and dont be afraid to call them


For us 4x4 guys picking a t case is the best place to start your v8 conversion, it will narrow your trans choices, which then narrows your computer choices and can help you decide what 5.0L to run, carbed, EFI or like me ODB II
 






Ok, Achen Auto has a 2003 4.0L SOHC w/ 67k on it and they want $750. Can someone tell me if this is to much? I don't know what they go for. Fox Auto has a 2003 w/ 20k on it for $1200 which I thought was pretty pricey.

I took a look at Advance Adaptors web site and I'm gettin a little scared...
"A4LD: The A4LD is identified by a "T" transmission code. The overall length of this transmission is 28.687". We do not offer any adapters to retain this transmission."

Soooo this means I'll never be able to upgrade to a 4406 in the future if I keep the 4R55E correct?
 






Ok, I just checked with Trans Parts Plus and they have a stock torque converter for $110 - a pretty good price considering that the dealer wants $320 + core ($253 my cost plus core).

I'm just concerned that I'll need a higher capacity converter with the 35s I'm running. They said they don't make one for my trans :( Does anyone know if the larger tires/gears will tear up a stock converter?
 






looks like I can get an '02 39K 4.0 SOHC complete with all accessories, mounts and manifolds for $1200.

I think I'm pickin it up on Tuesday
 






Well well well looky what I have aquired in my sig ;)

looks like the sohc won't be goin in my truck after all...
 






I think the SOHC is the way to go. i believe it uses the same motor mounts aswell. not 100% sure. and the SOHC got alittle more bang stock. its quicker and better on MPG, unless you going to tow, but the SOHC has enough power to tow too. Ford designed a good motor with the SOHC. and you can supercharge the SOHC, you will just have to drop the compression from 9.7:1 to 9.0:1!
 






Just saying you think it is the way to go because it uses the same motor mounts is leaving alot of things that need to be considered out.

What transmission you want to use will effect what computer and engine you run 100%.

The SOHC is a great alternative if you have a 5 speed, or want to bolt it to your existing auto transmission and keep your existing 4.0L computer.
It can be more $$$ and more work then the V8 conversion otherwise, and putting the SOHC in front of your current auto tranny is not always a good idea.

I am all for being different and I agree with you 100%, If I hada 5 speed OHV or was okay with a C5/4 automatic (no overdrive) then I would go SOHC 4.0L too
 






Thats not all im saying, but thats something i noticed.
