Question about 1986 Jeep CJ7
I do belive you are trying to put a 4.0L serpentine belt motor into a jeep that came with a 4.2L vbelt .It can be done . lots of trouble though. You should look at putting in the 4.2L engine with the 4.0L head, it will give you an extra 40 Hp over the stock 4.2L and you wont lose the torq.The 4.0L engines have less torq and sometimes come with efi, but this option would be better if your just going to use it on the street only.
Hope that helps, please take a moment to "Accept" my solution
Thankyou! Fellow Jeep Owner Here!

Hi, since these are a little older models, I am unsure if this is possible and I am assuming that you are putting the same size engine in for the swap. Here is a number to call to ask your question, ask for Norman and he should be able to answer any and all questions that you may have which I think is much easier than trying to type it all on the internet. Let me know how this goes and good luck

I wouldnt recommend swapping motors on different models, even if they appear to fit properly. It will always create some king of complication along the way, even if it appears to run smoothly initially.
I dont think they make cross over mounts for older models. You may have to get one fabricated. But you can try various mechanics in your town, who may have one.
Hope that helps. If you found my answer satisfactory, kindly take a moment to "Accept" my solution.
Thanks in advance,
