eaglescout526 Posted June 29, 2023 Share Posted June 29, 2023 Question. What is the question here? Are you wanting to know if you can swap the GM for the 4.0L? Yes you can, you need a donor Jeep to swap it in. Link to comment Share on other sites More sharing options...

JeepSchmidt O'Guinness Posted June 30, 2023 Share Posted June 30, 2023 IIRC, I thought the 4.0 wouldn't fit 86/87 engine bay without massaging the firewall. I could be misremembering threads or they were wrong to begin with. Link to comment Share on other sites More sharing options...

I could be misremembering threads or they were wrong to begin with. early 86s will need a big hammer whack or 2. later 86s already have the correct firewall.
