440 In A FSJ

[Jake_S]

I was curious if anyone has done the swap, or heard of anyone doing it? My '84 GWag has 197000 on the odo, and the 360 is starting to show the results of those miles.
I thought about rebulding the 360, but I have a 440 out of '68 police intercepter :D, so I got to thinking that it should fit w/o any major headaches, the 360 itself looks like a smaler version of a Chrysler big block.
I know I'll need the 727 out of a Dodge, and I'll need to change some of the electrical stuff, but besides that, are ther any pitfalls that I'm missing?

This would NOT be a bolt-in swap. The 440 is a Chrysler motor and the 360 is an AMC. They are not related.

[Stuka]

its possible..but I sure as well wouldent ever put a Chryco engine in my rig.

Dodge made just as good a motor as anybody else, especially if it's a big block. smile.gif
It won't be a bolt in, but nothing other than an AMC motor ever is. You should be able to get a 727 and a t-case from from a dodge, might be able to find a 727/208 combo on a dodge 4x4 and just swap the whole thing, not sure if it'll have a driver's side drop or not, but I think they do. That way all you'll need to do is pull the old stuff out and put the new stuff in.

Obviously that won't be it, but that may help (I hope). Here's a link to a guy that's swapping to a 455. It's not a dodge, but it's the same principle.

Hook the 440 up to a Chrysler 727 and switch the tailshaft with the tailshaft of a AMC 727. That should let it bolt up to your transfer case. Also 440 motor mounts would have to be put in.

Stuka, I don't like mixing different engine makes into Wagoneers (especially a sbc), but you have to admit that a 440 intercepter would run rings around a 360 (AMC or Mopar). Weren't some Wagoneers made by Chrysler anyway?

Go for it! As an old mopar car fan...I have envisioned this swap many times. In fact I have a 727 w/ Dana 20 adapter along with a 67 383 magnum just waiting for the right Jeep. Can you say zoom,zoom,torque,torque???

Jake, I've thought about this very same thing since the later wags have the TF727 instead of the TH400. I have not done this, so anything I say should be considered theory. The TH400 guys have worked out an easy swap to Chev SB, but that also has the luxury of available motor mounts. The idea with the Chev is to swap the AMC TH400 for a Chev, keeping the AMC tailhousing and original Tranfer Case. The work on the transmission can be done fairly easily so is a good do-it-yourself, or inexpensive for a tranny shop to do if you farm it out. I think that idea should work for TF727's as well. Take the original Chrys trans and swap the AMC tailshaft onto it (you are prob ready for a re-build anyway, right?) and then you can keep the original Jeep stuff, from the transfer case back. Now, here comes the hardest part as I see it, when you mount the transmission on the original mount, it will "set" the engine location. You should have plenty of room for everything, but you will have to make/fabricate/adapt motor mounts. Once that is done I don't see any problems that could not be worked out. Distributor is on the front, if you run out of "fan room" you could use an electric fan, A four row radiator should be enough to cool, and a Jeep alternator should take care of any poss electrical problems. I think it would be a really cool swap, and since I tow a 4000lb trailer, the tourque would be very usefull. :D

The only reason I have not looked further into this is money. I don't have a 440, and the 360 I have in it now is running pretty good since I replaced the timing chain and seals. I can upgrade my 360 and get reasonable results for a lot less money than buying a 440. But if I had a 440 sitting around, especially with a tranny too!!!! I would go for it. I would love to see one that has been done. If you do take pics and if you come up with a good motor mount set-up, that would be very valuable information.

[JOECOOL]

I can be done. I saw a few in J trucks when I was shopping for a pick up last year. It should be simple enough to swap the tail shaft from a AMC 727 to the 440s tranny.
Go for it Jake.

[scotty]

hate to break this to ya ;) but you will not have to swap tailshafts. the chryo/dodge 727 shares the very same 23 spline output and circualr new process pattern,letting you simply bolt on the new process case of your choice.

the little dodges use a driver side diff,and the bigger ones use a pass side diff.

i think if youre gonna swap a chrysler engine,it might as well be the 440 smile.gif

let the tranny/xfer position the engine so stock drivesahfts can be used and make up some mounts,the rest will be typical swap stuff.dont know enuf bout ther 440 to specualte if its wide enuff to give ya clearance prollems on either side...

keep us updated on the project.

think ill stick with my t18 and 6 cyl,tho ;)

[Jake_S]

Mahlman, I know that the swap won't be a bolt in, if it was, it would be too easy.
Joecool, the term interceptor was used by Chrysler in the '60's. That's what the book I used to look up the casting numbers said it was out of.
Thanks for the input guys, now I know I don't have to get custom driveshafts made, hopefully.
I don't know when the swap will take place, because the 360 is still going strong for now, but when I start, I'll let everyone know by asking TONS of questions. You gotta love this board.

When I was in High School my ex cop car. A 440 Polara said Pursiut on there someplace.
And the last time i was in the back seat of a Crown Vic cop car it said Interceptor on the back door window sticker..
Of course things change.

[Jake_S]

Well Joe, books have been known to confuse information between makes. I still think that Interceptor sounds better than Pursuit anyways tongue.gif

I say go 4 it! I have owned several Mopar big block cars in my days. There is nothing like having one of those stump-pullers under the hood.

Make sure you don't limit yourself to just looking into swap options with 4x4 shops. Lakewood sells a bellhousing now for just about any engine/tranny swap you can think of. So give Jegs or Summit a call.

If you want to go 4-speed I know where there is a Dodge NP435 and NP208 transfer case. ;)

[Jake_S]

Don't temp me with that 4 speed Al! I need to keep it an auto so the girlfriend will be able to drive it, not that she would anyway. :D

[Shake N Bake]

If you can keep em tuned that is smile.gif

Is there a question of the added torque and HP going to the NP 229 in that motor swap? Do they offer performance rebuild kits for the NPs? Probably a dumb question, but I don't know the answer.

[Jake_S]

Dive30, if I grenade the 229, that will give me a very good excuse to spend more money for a 208, or possibly an Atlas.
