Getting the Wheeling Fever
So, about this head swappin thing. I think I'd be willing to settle for a rebuilt 258 if I could get rid of stuff like that *(&*% carb! So if I get a 4.0 with MPFI and just take the head off of that, alter it accordingly, and put it on the rebuilt 258, I should have an MPFI 258...right? What all do I need for this conversion?

Yeah, after looking at it more I think I still have the same questions. I'm trying to avoid spending 2 grand on a fuel injection kit when I can spend less on just swappin' an already fuel injected engine.
One thing I saw from most comments in the articles is that people are putting a carb back on the 4.0 head. If they put on a fuel injection system, it looks like they're buying an aftermarket package. Since this is what I'm trying to avoid, I'm thinking that using the fuel rail, computer, and other parts from the donor 4.0 will work just as well.
Maybe I'm better off swappin engines instead of just the heads... <img src="/forums/images/graemlins/confused.gif" alt="" />

Another thing to consider, if you swap the engine and emissions control stuff from a newer vehicle (I recommend 91 YJ) it will pass smog better as a swap instead of a custom EFI job.

I would go for the motor swap. You get the EFI without the hassle of pulling the motor apart modifying and reassembling.

Yeah, I think the swap is the better choice. I'm going to rebuild the donor vehicle's motor anyhow. Actually, my mechanic buddy will!

One last (hopefully) thing on this topic...
THe 4.0 has an AW4 tranny. Looks like Novak has a $170 kit to adapt it to my Dana 300. What's going to happen when I try to mount the tranny after that. I currently have a T5 on the 258 and think that they're different sizes so I'll have to do somehing (weld in mounts, crossmember)? THanks

You obvioulsy did not go to www.cjoffroad.com. They have a forum completely dedicated to swapping in the 4.0L engine AND doing 4.0 head swaps and using the fuel injection off of a 4.0L motor.

I, and several other people on cjoffroad, have completed a 4.0L engine and AW4 drivetrain swap into a CJ. I have several threads on there with detailed pictures of how the swap went, the adapter from Novak, blah ble blah, ble blah.

Do your research. Maybe you just want to think that your idea is the most outrageous and unique but trust me, it has been done before several times and there are places and people that you could get more info than you can read in one day on it.

READ AND SEARCH!!!!!!!
