350 swap... need help

I'm putting a 350 into my yj. Now it comes with an auto trans but I want a manual. 5 speed or, more preferably, a 6 speed. I have the 2.5L 5 speed in my 93 yj base. But i don't feel like spending $400 for a conversion plate and it not even be that good of a trans. So what I'm wondering is if anyone knows which vehicles I can pull a transfer case and trans right out of at a junk yard.... now if it's too hard or too expensive I will go for an automatic but either way I need a transfer case too keep 4x4. Thank you....
P.S.- I'm new to the building world of jeeps. I have a zj I offroad with and I built alot of it but not the engine. I'm going to have help it's just finding the right parts. So dummy it down for me haha

The 2.5 liter 5 speed is not an option for a lot of reasons. I put an NV3550 (from a 2002) in my conversion but that required an adapter and also a change on the transfer case input shaft.

Check the Novak website for options that would be a direct bolt up to your engine. They have a lot of technical resources describing pros and cons of different transmission and transfer case options.

Otherwise I am sure someone with more first hand knowledge will chime in.

Theres no real cheap or easy way, unless you luck up on a deal. A thing you have to keep into consideration is length. A full size trucks drivetrain is quite long. That equals a short driveshaft. You could go Nv3500 out of an s10 but they are very long, as they have a non removable bell housing. Could also get a nv4500 but they are very expense, even used, I think the last one I saw on CL was like $800, without a transfer. A SM456 is a good option but thats a 4speed, then you'll need an adapter to get a driver side drop transfer. Unless you find one out a 88 up, which is fairly rare. Like Cruiser mentioned, the NV3550 is a good choice. But quite honestly for money and the ease of doing it an automatic is a great way to go, whether it be a th350 th400, or 700r.

With an adapter can't an AX15 hold up behind a 350? I know that the AX5 won't... but I have heard a couple of guys I know say that they have considered keeping the AX15 from the straight 6, and that would allow the NP231 to still be used, although you would probably want to get the wide chain.

I have a 350 in my 93 yj and Chevy 700r4 automatic transmission and Chevy 208 transfer case ( which is a driverside drop) so it mates to the jeep axles. Everything is a pullout from a 92 silverado 1500.
