Pick Some of Your Brains

I just had an idea and was wondering what everyone on here thinks. I have a 1979 CJ5 with a 304 motor that runs ok, but might be at the end of its life soon. I currently have a 2002 Jeep Liberty with the 3.7L V6, strong motor, and automatic trans, but not a 4WD. I plan on buying a new car for the wife in the next 6 months and was considering putting the 3.7L V6 and trans in the CJ5, would the rear axel from the Liberty work on the CJ5? Also, would the transfer case and stock front axel work with the V6? I am not an expert and would more than likly have a shop do the work. Would this cost just an enormous amount of money to do? Or should i just get the 304 rebuilt and fixed up?

Thanks

Your TCase would require a pretty expensive adapter to mate to the Liberty Tranny and probably wouldnt be that desireable anyway.

the 3.7L and tranny could probably be made to work but you'd have the shortest driveshaft in history on a CJ5. There are MUCH better engine swap candidates out there that can be done much cheaper IMO.

Automatics in CJ5's generally dont work because of the length of the transmissions resulting in steep driveline angles

What about just using the motor, think it could be made to work with the T-150 and transfer case?

To use the 3.7L, you're going to need an adapter plate. I'm not sure what the bellhousing pattern is on that engine, but I can tell you for certain it is not the same as on the AMC six and V8. The 242ci I6 was the last production engine to use that bellhousing pattern.

the libby motor has electronic throttle to so you will have alot of wiring. Yes a rebuild of the 304 would probably be cheaper if you have shop install the libby motor in the cj.

I agree 100% on the sell the liberty and put something else in the CJ. Heck I would think for what you could get for even a ratty liberty would be enough to fully fund rebuilding the 304, slapping a cam and intake on it and topping it all off with some kind of throttle body fuel injection. It would be way easier too, in my opinion.

Proving daily that I have gears for brains!

Just make sure it's an AMC 360 (say, from an FSJ or a J-series.) The MOPAR 360 is an LA-block, and would again take some adapting.

The AMC 360, however, will drop right in place (as would the AMC 401, if you find one...)
