I'm wondering if anyone has any advice regarding engine swaps? I've found a smallblock chevy v8 and a rebuilt sm 465 manual tranny. The engine has all the wiring, the computer, alternator. Jeep currently has a 4Cylinder 2.5L AMC, and an AX5 tranny. Am I missing anything or any advice before I buy it and start taking things apart?

Your going to probably want to trade out the whole drive train and beef up the suspension for this swap. What axles does it have?

The SM465 is a real beast, isn't it? Probably not going to be fun or cheap to mate it to a transfer case. Do you know which version you have?

As far as I know the axles are stock. I have a np231 transfer case which from what I've read should be able to take the sm 465.

Not a popular swap but I am swapping out the 2.8l V6 for the 2.1l Renault Turbo Diesel

Depending on what year you are probably running a dana 30 up front and a dana 35 out back. If that is the case a v8 will trash those pretty easily. Use this to try and figure out what you have or take pictures and post them here.

Do all Dana 44's have a recessed drain plug in the bottom? I had previously thought that drain plugs (as opposed to just popping off the plate) were a Toyota thing (where there is no plate, just a removeable third which is actually awesome, but too involved for just changing the fluid)? I don't remember my friend's XJ with a d44 having a drain plug (we sure didn't use it) - but the early Dana 44's under the Willys MBs and Ford GPWs at work have drain plugs (which is loving awesome).

 This is my rear axle, which looks like Dana 35, the front axle looks the same. So it looks like I need some new axles, any suggestions? I remember reading somewhere that Dana 44's were the way to go, this true?

Everyone says that, but IMO it is mostly true for when you are shopping for a Jeep. If I'm going to build an off-roader and will be swapping the axles (which if I were you I wouldn't do until those 35s let go, it could be a LONG time if you are careful with the skinny pedal - or it could be sooner) I'd go for Dana 60s or some other full-size truck axle. In my experience they are probably just as easy to find (there are a lot of 1 ton trucks in junkyards with perfectly fine axles), you will need to do some fabricating though - but you'll end up with an axle that can take huge tires + abuse and pretty much never break.

It depends on what type of offroader he is trying to build. If he just wants something with 33" tires I wouldn't go over a dana 44 because you are just losing ground clearance. Not everything need to be overbuilt. If he does want to go big then more power to him.

Maybe when one goes do both, probably not though assuming the rear goes first.

Right now I have 33's on it, I'd like the option down the line to put bigger tires on, maybe after these wear out. How light do I need to be on the gas so I don't rip these things apart? if they do collapse what kind of damage will it cause?

How light do I need to be on the gas so I don't rip these things apart? if they do collapse what kind of damage will it cause? As far as I've ever seen (and I've seen some pretty trashed d44's coming in on WWII Jeeps), if the axle goes, the axle will need to be replaced. I can't see any reason anything else will be damaged (axle shafts might be, but you'd be replacing those with the new axle anyway). I'm guessing they aren't full floated axles so if you really gently caress the axle bad you might have a tough time moving the truck out of where it happens. On a FF you can carry some non-locking front hub pieces and if you grenade the axle you can simply pull the axle shafts, install those pieces in their place (rear wheels are now free-spinning), and then drop the rear driveshaft off of the xfer case and tie it up and out of the way. Congrats you have a FWD Jeep to get you home. Process would be similar if you grenade the front, except you could just put it in 2WD instead of loving with the driveshaft and just unlock your front hubs if you have lockouts. That said I'm 99% sure those axles are no full floating so it might be a lot more difficult. Usually you'll have a warning sign before an axle go so bad you are STUCK where you are because it is so disabled.

BrokenKnucklez posted:How hard is it to drop in that 4.3? I always thought behind the 4.0, the 4.3 would be the next runner up, due to good amount torque on the low end, but have the horse power when hauling tail down the interstate. I was an awesome motor. I think it had about 215k on it when I sold it. Speaking for YJ's At the time, the options were limited. The best was getting an adapter for a 2WD sm465 transmission (chevy 4 speed) this one is nice because it has a PTO option for all kinds of fun stuff. At the time only Advance Adapters was making an adapter to mate to the NP231 transfer case. The second best option was to use the Jeep AX15 (5 spd came with 4.0L or 4.2L) with a special bellhousing that allowed you to bolt up to the Chevy 90º engines. Right after I got done they came out with the NV3500 to NP231 adapter. I don't know if they had PTO but they had that nice overdrive gear for the highway. There was also a TH350 to NP231 adapter for the automatics. Back then it sounded a lot easier than it was especially when you threw in fuel injection. Nowadays there's at least 3 different companies making countless adapters and wiring harnesses, it just takes some research and general know-how.

Well we had a good rain storm last night which means I had to go for a little drive. The area is all red clay and sand, so there was a lot of washed out ruts and mud puddles. I did get stuck leaving because I put it in 2wd and then hit a mud puddle at the bottom of a small hill that was hidden by grass. I have to say that driving through loose wet sand it more fun than I would imagine.

Yeah, bottom of the diff on the military ones (I don't know if a CJ2A axle would be the same, possibly) has a place for a 1/2" square drive (ie ratchet) to drain from the bottom. It is totally recessed/flush with the housing which is probably why I never noticed it in 3 years of loving with those old heaps.

MB's and GPW's didn't use D44's, which is why you're confused. D44's don't have drain plugs in the bottom. D44's showed up in Jeeps starting with the CJ-3A. You're probably referring to Spicer 23's if you're talking about MB and GPW Jeeps.

They have covers that pretty much look like 44 covers. I just looked in the US Army manual and it is a Dana-Spicer 23-2 in the rear and a Dana 25 in the front. There you have it.

Just a friendly reminder to everyone to get and and exercise your transfer case. I really love my cherokee. No I didn't go all the way over. To little ground clearance and to much rebar sticking out.

This is our friend's Jeep. Unfortunately this was taken from ours, which I can't seem to find any pictures of currently. I will update when I can. Onto the Jeep love:  Bonus points if you can guess the model from the pictures! PS Its a CJ-8 Also, I'm terribly sad. My first car was a '98 TJ, but I have since been forced into an '02 KJ.

That particular CJ-8 happens to have an I6 from an '06 TJ if I'm not terribly mistaken. He also managed to rig up a bike throttle to do cruise control/crawling with that works amazingly well for the application.

I'm hoping it's just the line to the cooler. It was leaking at the cooler earlier, so I should just replace the line anyway. I think I gotta rebuilt the tcase, too, so I hope somewhere in there the problem will get fixed.

The body looked great, but the back window was stuck down so there was probably rust all in the cargo area. I haven't seen any 401s since. I should have bought it. The rust wouldn't scare me away now. Cherokees are so badass too.

Anything wider will rub on your control arms (need new rims), and anything taller will definitely rub your fenders. Edit: 30's may still rub your suspension even from the factory. You're 100% safe with 235/75/r15 if your leafs aren't sagged. I'd still go with 30's though. MrZig fucked around with this message at 02:20 on May 20, 2008 |

But seriously, I don't think FSJs are going to get that much more expensive in the future. You can still get J trucks for pretty cheap now. I can see Cherokees and J trucks getting pricey, but there will always be Wagoneers around.
