Well, it’s alive!.....kinda. Finished installing the flywheel, clutch, transmission and bellhousing, etc etc. Went to fire it up and it dies after 2-3 sec max. From all the research I’ve done, it seems like more than likely the SKIM system in the ZJ ECU I’m using. I didn’t plan on using this ECU long term anyway, since it’s for an auto trans. Heres a video!

Only codes that I have are for the evap(not hooked up yet), and the auto trans, so this still leads me to believe it’s the SKIM system. Will be testing it with a certified non skim ECU to rule it out. Only other thing it could be would be the ASD being wired improperly. I feel like I wired it right the first time so let’s hope that isn’t it. Was an amazing feeling though when the engine fired for the very first time!

Here's a tip for people who have worried about getting the transmission mount in place since it obviously wouldnt reach the stock mounting location, IF you place the AA mounts in the recommended location and you're using a manual transmission. People talk about needing to beat in the firewall, and all sorts of stuff; barely being able to get the transmission mount holes to line up, or having to fab up a trans mount out of 2 different mounts. I just bought the Barnes 4WD skidplate, which has a ton of front-to-back adjustment for where you're transmission mounts can be placed. This made mounting the transmission EXTREMELY easy. Just a quick tip. Here is a link to the skidplate.

That's awesome! Great progress so far, sounds good even for running for only 2 seconds. Hopefully you figure out what the cause is that is keeping it from running for more than 2 seconds!

Thanks! This is a common problem when people do this swap, I'm pretty sure it's more than likely the SKIM system inside the ZJ ecu.

Its alive! Tested it with a verified non-skim ecu from a buddies Jeep and it fired up and ran great! Such a good feeling knowing that I did the wiring correctly, etc. Now for all the other items: radiator/cooling system, driveshafts, and exhaust and it will be driving on the road! Also have to do something with my shifter but I have a pretty good idea of what I'm going to do, based on what I saw another member on here do in his build thread. Stay tuned!

Its starting to look like a Jeep again, installed the radiator, ZJ clutch fan, and 4.0 fan shroud, which all worked out perfectly.

Here’s the flex radiator hose i used. I also got silicone adapters to attach it with t-bar clamps. But you can probably find rubber hose adapters even cheaper.

Great job so far and love seeing these V-8 swaps into the TJ's. I have a 5.2 in mine right now but am building a 5.9 for it that I have a stroker kit for so it will make it a 6.7 (408) when done. I'm running a 46RE tranny with a STaK's 3 speed transfer case.

I must have missed it but what radiator did you use? Are you using a mechanical fan or electric? I'm sure you are getting super excited about getting this done and can't wait to drive it again. If you are looking for any performance parts I have some I have bought that I can't use for my new engine.

Please detail what you do with your shifter. (I assume it's a manual). I have modifications to do to mine after putting in a Chevy 5.3 for the same reasons you do, but the bending and adding length to the shifter will probably have to be pretty drastic.

I just used an OEM radiator. There are several of these swaps (that were kept stock) that used the OEM radiator and they cooled fine. If I have any issues, ill upgrade it to an aluminum one, but it seems like more times than not, even the big name brand ones seem to leak at the welds. And for the fan, I just used a ZJ mechanical clutch fan and a 4.0 fan shroud.

I certainly will. I am pretty sure what I am going to do is cut the shifter at the bottom, add a small 2.5" plate to move the shaft back and weld it together. I got the idea from another member on one of the forums, and it worked well for him.

So just so I understand correctly you are using the stock ZJ radiator? Did it just bolt up to the TJ?

Yes I agree many aftermarket radiators leave a lot to be desired. I have had two different ones in my TJ so far and the aluminum one is a piece of junk that COST way more than I should have spent.
Due to my engine placement I have to run a electric fan but sure would like to try a mechanical fan. Might have to look at what I can do with that.

I would suggest bracing that plate. Helped stiffen up my shifter. I can get a picture if needed.

No I am using the TJ radiator. ZJ radiator wouldn't fit. I trust a brand new OEM radiator more than an aluminum one. Even the "higher up" brands have been known to leak. If one day down the road I have an issue, I can always change it easily.
