    Thanks for this tip on motor mounts. I’ll save that info just in case.
    I think it’s gonna be okay but good to have options

    The problem isn't with it "fitting" into the engine bay. The 3.7 has a very narrow profile so the engine is taller than the 5.0 and then the 2007 hood might not fit

    I thought the cyclone was a coyote less two cylinders?

    No, they are very different engine blocks.

    The Coyote is a 90 degree V and the Cyclone is a 60 degree V so it’s narrower and taller

    I hooked up the battery just to check things out. I didn't try to start it yet, I have no gas in it and no exhaust yet. I still need to add coolant also. Anyway, I found that the doors need the harness's swapped. Long story short, everything inside the doors is pretty much different. I had to swap the window motor from the 12 onto the 07 regulator. I had to change the window switch and the door latch. So now I have the drivers side door all converted over including the door lock so the 2012 key works in the 07 door. Now I have to do the passenger door!

    Admire your drive, but I feel like you could've treated this like a Coyote swap and how I did my 07 GT Coyote by merely hard wiring the body connector at the PCM and everything will work, like AC Cruise etc.

    so your saying if i got a gen 1 5.0 and pcm i can rewire it too work as is? i did see your links for youtube ( quite the work if you ask me) but well worth it, i just didnt know cuz i saw where you said it was like $3500 without the motor?

    Yes. Exactly what I’m saying. And the 3500 was mostly other parts like headers etc. the wiring would almost be nothing but you do have to buy some harnesses etc anyways. Way cheaper than buying a 2000 control pack and then still having to wire it

    Since its now basically a '12, a 5.0 swap would be way easier than what Matt and I did. lol Should be practically plug&play.

    well I am not confident in rewiring stuff so I figured I could just swap the wiring itself. Which is what I have done. I bought the 2012 for $1300, sold my 4.0 auto trans for $500 and variaous other parts like the wheels from the 2012 and so I have hardly any money in this swap. Just my time. I work on it on the weekends for a few hours. I hope it will run!

    I am hoping to get some time to work on it today. If all goes well I should be able to try and start it this weekend!
