Advanced Adapters is where I read about the 1" body lift.
Oh its worse then that I am swapping in a 5.2L. I have a reputation of making bad decisions. But I found a ZJ for $500 and thats pretty much why i chose it. The Magnum motors have been swapped and well documented.just curious, but why go with the 5.9L vs the seemingly more common 5.3 LS?
Because with the Dodge motor the PCM for the V-8 talks to the stock dash. There is some wiring that needs to be redone but it isn't anything like doing a LS swap. It is also more economical than a LS swap.just curious, but why go with the 5.9L vs the seemingly more common 5.3 LS?

gotcha. I just didn't know if there was some advantage to it that offset the 40-ish horsepower and probably 5mpg deficit it has vs the LS. But "I already have the donor vehicle" is a good enough reason I suppose.
I've been swap-curious for a long time but I'm still 3 years out from having what I consider adequate facilities to do one (my HOA limits number of vehicles parked outside and entirely forbids non running vehicles parked outside, which means I need to build a shop to have room for the donor and recipient vehicles) . I always figured I'd go with the LS but if there was something about staying Mopar that made things significantly easier or produced a superior final result I could definitely be swayed.

But Dodge stopped making the magnum V-8 in 2002 with very few in 2003 so if you're trying to stay EPA legal if you own a newer TJ you either do a LS or Hemi swap.
I'm not sure where you got the 5 MPG better milage from but my only experience with a LS engine was in a truck with a 6.2 and I hated that engine.
My 5.9 stroked to a 6.7 won't be any slouch for power. I'll agree the LS engine can be a good engine but with the ease of the Dodge magnum V-8 swap unless you have a newer TJ I'd still go with it. With a little bit of engine work you can be making 300HP/Torque.
Plus I like being different. And Jeep/Chevy engine swaps are just too sheepishly to me.
My mpg comparison was unfair. I saw the 1999 Ram 4x4 5.9L was EPA rated for 12 combined, and compared that directly to my real world results with the Silverado which sees mostly highway miles. The Chevy was only rated for 14, so I wasn't comparing apples.
Power-wise, I'm just comparing stock for stock. I have a 2000 Silverado 5.3 in my driveway, get about 17.5mpg with it and it was published to have 285hp vs 230-250 for the 5.9 Magnum depending on the year. Yeah, 6.7L will be no slouch, holy moly! And though noise isn't what I want in a Jeep, Mopar motors always sound way better to me than Chevys do. They have that gorgeous musclecar roar where Chevys to me sound like an old farm truck with glass packs.
I'm not talking about your local EPA laws I'm referring to Federal EPA standards. If you swap a engine from a older model year than the year of the vehicle it's being swapped into it's illegal to sell it. Plus if for some reason they did start doing smog checks where you live would you want to not be able to license it?
Keeping it smog legal IMHO doesn't hurt performance so why not keep it legal.
Yes the Hemi can be made to talk to the stock dash easier than a LS.
You get about the HP numbers from either.
You can't use the MPG rating from a heavier vehicle to compare in a Jeep.
If I were building an older jeep, like a cj7, there is no way I would put a magnum 5.2/5.9 in it. 5.3 Chevy with a small cam, 4l65e trans, and motor on. The reason is most CJs need to be completely rewired at this point, so so are basically starting over anyway. This would include YJs also.
TJs are another story. If you want over 400 hp cheap( relatively) put a chevy in it. If you want an swap that is easy to make look factory, do a magnum. It's easy as far as v8 swaps go ( I have done ls, small block chevy, small block ford, magnum) , no t case adapter required, uses the same basic pcm, gauges work, etc
Now before the ls crowd jumps in, yes, it is a badass platform. But, it isnt as easy or inexpensive as a magnum ( in a TJ ).If I were building a no holds barred, let's go son of a bitch I would use a ls Chevy. My Tj with a 5.9 and a little cam runs with the AMCs and SBChevy CJs my friends have. I cant run with the 5.3 or 6.0 Chevys.
It's all doable and all engines have their pros and cons.
If I was building a CJ or even a YJ I'd put a TPI 350 stroked to a 383 in it. But that is because I've always liked that engine. And as I said my only experiance with the LS engines was the 6.2 I had and it SUCKED. It wasn't good on fuel and didn't have the power I thought it should have had.
