Not too bad for a Cherokee, and wouldn't kill the wallet for the swap or to feed it either.  It looked like a clean install, anyways, in the first video.

Take it from somebody who had one; not even close to worth the effort. 

Stick a good granny gear manual behind a 4.0 and you have a more reliable, easier to service power plant that will deal with being flopped onto it's side better nad has a superior torque curve.

Yes, shame on me for expressing an opinion that was not the same as yours…  Dream all you want and do what you want; you don't need my approval.

You may want to look a little closer into what exactly you are buying on the old Jeep because first of all there is no such thin as a CJa or CJb.  I assume you are talking about a CJ-3A and and CJ-3B and I am not sure if there was overlap on them or not so you may want to double check the years on the frame and motor.  

Also check what axles are under it, hopefully they have been upgraded to later model axles, because to be honest with you if you have a granny gear and a strong F-head you are going to have nothing but headaches axle wise; the two piece D44 is prone to spinning the flanges on the axle even more than that AMC 20 and unless it has an updated t-case the pumpkin is going to be on the right side and axles are hard to find.  The only real upgrade is to get a '70 and up one piece diff or look for an elusive Qudratrac D60 and cut one side down.  Plus the D25 or 27 it had in the front from the factory is not very strong and can be difficult toget parts for and to service.

Not to mention a 53 is going to have thorugh the floor pedals and a single resivour master cylinder all of which suck. The frame are also very prone to some pretty serious structural issues unless you put some significant work into reinfocing them.

Old Jeeps are awesome but if it is not a complete vehicle in one piece or you are getting a freaky good deal (Like damn near free) they are just a big headache.

Mind you I am not discouraging you from getting into an old flatty, just cautioning you to really look at what you are planning to buy vs. what you want to do with it and what it will take to get it there.

Remember, my all time favorite trail rig is the Pewe Flatty; which died of a broken frame.

More than once.

Man, I wish I could find the pic of it broken in half; if anyone can find it that would be soooo awesome.

The parts in the back are for a 3A, they will not fit with the f-head; it was the reason for the tall hood on the 3B.

Looks like it has stock axles, an unboxed frame, is still running the 'c' style shackles and high count spring packs; it would need a ton of work to be ready for all but the easiest trails.

It does, however, look to be in excelent shape but I am having trouble figuring out what trans could be in it because it looks like the T-90 that came in a 3B and that is only a 3spd.

Low range int he D18 sucks but too.
