After the radiator and alternator were installed I decided to upgrade the wiring to the battery and solenoid.


This is what the terminals and wiring look like originally.

All the connections received heat shrink that had adhesives.


I’ve been changed out quite a few of the vacuum lines to silicone lines.


Moab is getting closer.

When I was wiring up the fans I had to change the thermostat housing with one that had a bung for the thermostat switch.


The relays for the fans are mounted on the passenger side fender well.


I also wired in some lights but unfortunately I did not take any photos. The reason I can’t go out and take photos now is because my Bronco is having the drivetrain changed.

Here is where the hating begins

Now it’s time for MOAB. We hooked the goose neck behind the Toyota Tacoma then loaded the Bronco.

Now it’s on to MOAB.

The first trail that we ran was Hells revenge.


After doing what we could do on Hells revenge mostly watching others play on the different obstacles we went back to camp



We determined the transmission was slipping too bad to continue on any of the more challenging trails. When we were able to get the transmission to lock up the motor was too weak to complete the obstacles.


So this is where we determine a new drivetrain was needed. As I said get ready for the hate.

So... what did you put in there?
Based on the ports for the water pump and the wiring harness, I'd say that's an LS engine. Which specific version? We'll have to stay tuned!

Looks like an LS with a 4l60e to me. It has the bell housing bolt at the very top of the transmission and you can see the 2-4 servo on the front passenger side sticking out.

No hate here. Cant wait to see how it turns out!

You are correct it is an LS LQ9 6 L with a 4L60 E transmission and an atlas 2 speed transfer case. When I started doing the research for the engine swap I wanted a more modern drivetrain that could be programmed easier and with a wider range. In the beginning I looked at doing a coyote swap, but it was just outside of my budget.

At this time the thread blasphemy came up and that made me start thinking. I posted on the AZ forum a question about engine swaps. A couple people suggested an LS.

I looked into the LS swap and found it is inside my budget. The swamp for a coyote was going to cost $22,000 and I could only find 2 shops that could perform this swap.

The LS swap cost me $18,000 and I found 5 shops that could perform the swap. I was referred to Flatiron Garage by Dirty Dingo Motorsports. They were not the cheapest of the five but Leonardo Cruz inspired a great deal of confidence.



Here are the motor and transmission mounts.


Big hole really big hole.


Now it is filled with a LQ9.

Here are some of the photos sent to me by Leonardo.


He promised me quite a few more photos of the process of the LQ9 swap. When I get them I will continue with my build.

Love the atlas! What ratio is it?

In case you arent aware, there are kits available to make the LS look more like a normal engine. The one that comes to mind reorientates the coils and covers them with normal valve covers.

Do you have any specs on the LQ9? I see it has the cathedral port intake runners, that's a good thing.

I'll give you a little hate..... on how nice all the vehicles keep out in the desert.

Almost makes those 110 degree days worth it. I have been flying into Chandler Arizona every 6 weeks for the past year. I started in August and I thought it was crazy to live out there. It was like everything was dying under that relentless sun... and then I flew back to Georgia and had to cut the grass every weekend because everything was green and growing... with plenty of rain. Then November and December came around and I got it. I thought Arizona was the promised land. I have definitely considered moving out there. I just have this fear of not being able to bug out on a moments notice. If the Nukes flew tomorrow I would take my Bronco..... find a set of rail road tracks heading north.... and get the hell out of the city as fast as humanly possible. We have some really cool mountains in North Georgia, Western North Carolina that I would have no problem with living off the land. If anything even remotely crazy happens in Arizona... It is going to be an all out steel cage death match for water...… and you guys have some of the easiest laws to own firearms... so if you don't have water good luck taking it. You cannot get out of town without water, and there isn't any falling from the sky.... You are stuck hoping your ammo doesn't run out before your water supply.

I'll take off my tin foil hat now.
Never let your ammo supply run out...

I’m definitely interested in the LS swap as I will be starting mine soon. $18K seems like a ****ton of money for the swap though. Engine should be under $4K with some rebuild work done, trans maybe $2K, and the Atlas are probably $3-4K now, so that leaves $8K for labor?

I’ve been researching LQ4 and L96 swaps with a budget of more like $5-6K, granted my truck is a manual trans that will take a GM bell housing and I won’t be going with an Atlas. GM released a control pack for the L96 engine, so that is my focus at this point. Lower mileage pullout engines look to be about $2K, the GM control pack is $1600, Novak sells most of the parts for the clutch swap for about $500, and I’m figuring another $1-2K in miscellaneous fuel system parts, AC lines, etc. I’m planning on doing the work myself. An LQ4 or LQ9 could be done cheaper so I’m not ruling those out, it’s more a matter of what motor I find in what condition first. The harness and computer for the LQ are cheaper than the control pack for the L96, everything else is about the same. I would also consider the 5.3, any LS option should be 100hp/100tq better than my 302.

@BroncoAZ you are absolutely correct doing this project yourself will save you a ton of money. Unfortunately I am not a mechanic, there are quite a few things I do to my Bronco but I wanted this project to be flawless. I got estimates from five different shops, they were all between the 15,000 and 20,000 range, flat iron garage was not the cheapest but he installed more confidence than all the rest of the shops.

I have a 99 F350 with a Dana 60 front end and a sterling 10.5 rear differential. When my budget allows these will be rebuilt and they will be put under my Bronco. I have not yet decided whether I will attempt to rebuild them myself.

OK, back to the build. Here is a few shots of the motor and Atlas installed

Once I get it back, hopefully this Friday, I will be able to provide much more detailed photos.

Holy Crap! How have I missed this thread?

Future FOTY truck right here! Awesome build & I wish I could see it in person! Guess I'll just have to settle for subscribing to the thread.
I'm sure you'll get a few disapproving comments about a LS swap in a Ford, but not from me! Great engine! It would be interesting to compare your truck to some of the diesel swaps once it's done.

When I got back from my last outing I pulled Crossbreed to the Bronco barn to do a once over. When I attempted to back out the rear differential locked up.

I pulled the rear driveshaft and was able to push the bronco out of the barn. I contacted Yukon Gear and Axle, and ask them what could the problem be.

I was told the pinion preload had gotten lost. The differentials were rebuilt by Arizona Differential so I decided to give them a call. I was told to bring the differential in and they will check it out. I drop the differential off on Monday and the following Friday I called them to get a determination on the problem.



I was told there was nothing wrong with the differential the pre-reload for the bearings was 6’ lb. there was a few other things I was told that did not make sense.

I just decided to check the preload for myself. With all the running gear together the preload was maybe 6’ lb. I tore the differential down to just the pinion. I could spend the pinion freely with almost no resistance.



I finish the teardown on the rear differential leaving the axle races installed. I ordered new seals and pinion depth bushing to replace the crush sleeve. This is where it sits now. Oh yeah please don’t say anything about my welds



I welded the tubes to the center section and the truss to the tubes. I did not weld the truss to the center section. I did one side yesterday by heating it to 375°. I started on the other side this morning and it was 30° out. Could not get the cast above 200°.I waited until around 1030 and it had warmed up to 65°. Welding went fine.
