Once I've completed that document, I'll start going over everything with everybody else who has done the swap and post what they're comfortable with.

After that will be a section for things to look out for, little tricks to do, and things to get around. Along with all that will be a complete history on the 318/360 engines and what types there are, along with what vehicles they came with and what transmissions came behind them. It's a long arduous process, but if it helps out a lot of people in the future, I'll be happy. That's the whole reason I'm wanting do it.

My intention for that group is to create a 5.2/5.9 magnum swap how to guide. Link it, tell people to read thread x, and all the info they should need is in there.
I'll be glad to contribute what I can to a guide. That would be an awesome resource for future swappers.

Can you elaborate on the AX15 comment? I am about to put an "unknown" AX15 in my '91 YJ that is likely to have come from a Cherokee mid-nineties but I also have a AX15 from a mid-90s YJ.

RE: "bad information" - you mean like the advice that I got that went along the lines of AX15 has a steel/magnetic center plate, AX5 is aluminum? Well, the two AX15s I have contain aluminum center plates, and the AX5 out of my '91 has a rusty steel center plate. Opposite of what I was told LOL!

The difference I was referring to was in the pilot tip. The tip of the output shaft that goes into the pilot bearing. The earlier ax-15's had a smaller pilot tip.
The other difference is in the throw out bearing. If you have a 1991 than you should have an internal slave cylinder/throw out combo. The later ax-15 designed for the external slave have a different bellhousing and a different front bearing retainer. That is the part that bolts over the output shaft. The bearing retainer designed for the throw out bearing has a sleeve attached to it for the newly designed throw out bearing to attach to.
I think that's it. If I remember more I will post it.

IM currently collecting parts for this swap, using a NV3550 with a 5.2L AX15 belhousing.

I tried to sub here with my normal username, but it seems 2xs has been taken, so:

Ignore the GM swap stuff... and slice you already have your engine started, you are far ahead of me.

The later (larger) pilot tip is the same size that was used on the dodge 5-speed, so you can use a stock Dodge pilot bearing. If you have the earlier (small) pilot then it gets a little more creative,what I did was to buy a Dodge pilot bearing. It uses a sleeve that presses into the crank and the bearing presses into that so I had the sleeve machined to fit the early yj pilot bearing that has a larger outer diameter but a smaller inner diameter thus retaining the use of a stock yj pilot for ease of replacement parts. It cost me $20 at the machine shop.
