Alright so my 4.0 needs to be rebuilt, crank is warped, bearings are shot. I dont really want to do all this on my back so I was planning on pulling the motor. I already have a new crank that I got a while back before I started the axle swap/long arms. Would it be more worthwhile to swap a 5.2 in? Ive been dreading the rebuild on the 4.0 ever since I started this thing, and I just dont know if I feel like putting that kind of time and money into a 4.0.

What would be involved in swapping an obd-1 5.2 into my jeep. It seems to be pretty straightforward, I just need some advice and input as far as the differences in wiring, it seems to me that as long as i have the 5.2 ecu it should be pretty easy.

Mounts and wiring is totally different. I wanted to do this but decided against it. Might as well do a SBC swap.
If you don't have a ton of stuff into this one buy a V8 ZJ and swap everything over.
