Thats odd, I guess they revised the block at some point. The way I would do it would probably be to either grind that top boss down slightly, or get some custom mounts made. I don't think you cold shim the bottom and still make it fit in the engine bay correctly.

i am hoping to swap the 4.0 into my 86 cj. (currently has 258). i was wondering if for pure simplicity of the whole project could i swap the 4.0 block only. i already have done the 4.0 head swap and was hoping that i could use the carburetor and not have to deal with most of the wiring.

the setup i was thinking was:

4.0 block
4.0 head
258 intake
2100 carb
electric fan
4.0 water pump
t-5 transmission



and i am also not too sure about what all takes to mount the engine to the transmition so any knowledge you have on that would be greatly apprecitaled

Tranny will bolt up, will just have to figure out how to make a clutch work correctly and the pilot bearing and such. You could go that route, but why? You'd actually lose a little power to gain a few RPM's the way your talking. The only reason I would do what your thinking is if I lost a bottom end. The FI is what makes the 4.0 swap so desirable to most.

yeah. FI is gold.

However, i am planning on getting a 4.0 block and building it into a mild stroker. i would be much easier for me to build the engine with it out of the jeep (but thats a given). i do not have any other form of transportation to work or school (i am in college). so i was planning on swapping the block and leaving everything else for a little while that way the jeep would not be out of service for as long as doing the whole project at one standing.
doing it like that would also give me a little chace to regain bank.

and when you say FI,
are you refering to MPFI or something TBI

MPFI, the full Chrysler swap. TBI is nice, but it still has a habbit of acting like a carb sometimes because of the way it works. The way im imterpreting what yous aid you just dont want to be without a vehicle while stroking it. Why don't you just stroke it before the install, that way you don't have to take it all back out to do the stroking. A 258 for the stroker parts can be had for extremely cheap, or even free.

sorry, i meant i would build the 4.0 stroker in my shed or somethin while the 258 was in the jeep and the jeep was still drivable. then when the 4.0 was finished i would swap the block and then at a little date swap over to the fuel injection

You could do what you said, but I'd honestly just do it all in one time. You can do it in a long weekend if you do your research and have everything you need there. My odd things you needed list was:
Fuel pump- Everyone says E2000, had one, didn't cut it for me. I got a Walbro universal and it will shoot fuel 10-12 feet from the schrader valve.
About 10 ft of 5/16 stainless fuel line. I used it to go around the front crossmember to hook up to the factory fuel inlet for the 4.0. Much safer and more professional looking than draping around some FI hose.
Low and high pressure fuel filters. I was always told to use 2, didn't want to chance it with my $100+ fuel pump and expensive engine.

They also cost an outrageous sum of money. I'd much rather take some time to make my own than pay for that.

How much is it? Is the price comprable to the hesco harness?

Yeah, painless is giving it to you with no KY lubricant on that one. You could pay a shop to do the harness for you and come out ahead.

very interesting and informative thread, the 4.2 in my CJ7 is very tired and i was going to replace it with a 304 or a 360 but after reading this it seems I will go with the 4.0 as fuel injection sounds liek the way to go. The best part is my step dad has a junkyard with a 92 cherokee with a 4.0 HO and 5 speed sitting in it. My plans are to use a 4.2 crank and rods to make a mild stroker. will the ax15 tranny out of the cherokee work in my 82 cj7, i think i would just need an adapter to use the d300 transfer case? Everything i would need would be in the cherokee correct? let me know how this all sounds!
