I'm thinking about swapping a 4.0 for my 4.2 in my 87 YJ so that I can get the FI before I bring my Jeep up to Alaska. My question is are there any companies that sell a 4.0 crate engine that would replace my 4.2 and still work with my stock manual transmission, and still be able to pass smog in California. Also I'm thinking about replacing my t-case, are there any companies that would sell a brand new t-case that would replace the stock one. And I'm not looking for an atlas. I know this might be considered Newbie stuff so if the Mods think it is move it, but I wanted to post it here because I think that it might get looked at more, and that way I might get more feed back.
