So you picked up an S10 27 spline input shaft with 6 planetary gear...is the 460LE or whatever it is 27 spline too?

Yes and yes the 4L60E is a 27 spline. Don't quote me on this but I'm fairly certain the 4L60E/700R4 are all 27 spline. The major differences are the 4L60E went to a 2 piece case (removable bellhousing) in the mid/late 90's sometime and the rear bolt pattern changed to a 6 hole pattern at some point as well. After posting this on another forum a member there said not all the early S10 cases had 6 pinion planetaries. I guess I lucked out. They all did have wide chains in them though.

Thanks for the clarification. I actually had a 6 planetary gear set from a random case but disposed of it because I had the wider teeth version and my case in my 99 has the sharper teeth. If that makes sense lol. Guess I should have kept it.

Got my transfer case all buttoned up. Gave it a coat of paint too. You can see in one pic below I had to bore out and tap the VSS hole to M22x1.5 for the 05 VSS. Had to make a little spacer to go below it too. Also got my adapter plate drilled and tapped. Just waiting on a new countersink from McMaster so I can finish the other 6 holes. Should be able to bolt it up this week sometime-
I ordered a bunch of exhaust tubing too so I can get that finished. Hopefully I can hear this thing run in the next week or two.

Yeah I'm getting pretty anxious to hear it run. I'm close though. Once I know it runs then I can pull the motor/trans back out, finish cleaning underneath and in the engine compartment and start cleaning up and looming the rest of the harness, run some fuel line, build a fuel tank, finish the exhaust.... lots more to do still
Then after that, this thing is getting a freshly rebuild set of axles under it too. D44 rear with limited slip, D30 front with selectable locker, 4.10 gears, big brake kit on the front and a rear disc swap too. After I'm done this will have nearly a 100% new drivetrain in it. I need to get this sucker done so I can start on the new trailer

All true statements and they are a strong axle for sure but they are 1.5" narrower than the stock XJ axle and are also a c-clip axle. I already have 2 XJ D44s on hand so I'm going to stick with that. I am using 8.8 discs for my conversion though
This XJ build along with your previous trailer are truly awesome. I'm always impressed by your work. I would love to build an XJ with a healthy V8!
Serious question though, regarding the rear axle, why an LSD over some type of selectable locker? Is there a benefit to using an LSD? I'm assuming you can set it up to slip as little or as much as you want before it fully engages. Reason I'm asking is I have seen a few built XJ's in my area using an LSD in the rear but a selectable locker up front... I get the selectable locker on the steer axle...

Thanks for the nice comments dms02c. I'm a believer in having a front locker in off road vehicles over the rear. Typically selectable lockers are not a limited slip when not engaged and I want to have better traction on the street when in 2wd. Torsen LSD diffs seem to be pretty good at distributing power equally so I decided to go with one of those. I don't think they are adjustable though. I haven't ordered any parts for the axles yet.
I got my countersink and studs in so I finished up the adapter plate this weekend and got the tcase installed.
I also ordered an exhaust system. Some assembly required

I think I need a bigger truck!
Great build thread... an LS in an XJ is a sweet combination.

I totally missed this project. Great work Jess!
Thanks guys
Don't forget... I am trying to document this swap on youtube as well. 5 vids so far with more to come:

The motor swap is looking good. Were you able to clock your transfer case up any using that adapter plate? I have a plate for my FSB, but have not yet installed it. I would have to second the recommendation for using an explorer 8.8. It is a solid axle, and the c-clips wouldn't make any difference with a torsen diff. It has no clutches to wear and create clearance for the clips to fall out.
