V8 CJ drivetrain in a YJ

I have access to a V* CJ that has been sitting for a few years but ran when parked so the drive train is good but the body has seen better days. I was thinking about taking it as a donor car and removing the entire drive train and putting it in my YJ. I was thinking about swapping out the 304, tranny (manual) and both rears but not sure if it would all fit. Anyone have any experience with this?

if you're looking to change everything over, might be easier in the long run to just put your YJs tub on the CJ chassis

mot sure if its a narrow track or not. havent checked. need to go take a good look at it. Was trying to see if it's even worth the trouble. The frame is shot so changing the tub wouldnt help. My YJ is extremely clean and runs well but I would like to upgrade the grears and would like more power. PLus its an auto and I would perfer a manual. so my logic was thinking about taking the rears, tranny and motor and swapping them in. If there 2in leafs how would they bolt up to my 2 1/2's?

Just my opinion, but that's a lot of work for no fuel injection...

Measure the axel length of the cj vs the yj some of the early cj's had narrower axels. It would probably be better to sell the cj them put the money into a 4.0 swap or get another 4.2 if your tranny is in good shape

I agree with above, that is alot of project for no fuel injection. ALSO, check your local laws in regards to engine change outs. IIRC, alot of areas require you to swap equal year or newer unless its a classic car.

Also your going to need a clutch petal assembly for a yj whitch is hydraulic, cj's use a z-bar for a clutch linkage which is a pain in the butt. The cj I had, when I would pull into my driveway would flex enough to allow the clutch to engage when the petal was depressed. Sometimes made for an interesting stop, they make a hydraulic conversion kit for cj's. also is the Dana 20 axel on the cj's any better than the Dana 30's and 35's
