What engines fit?

I've seen links on here before (probably from Bill) and after going through Bill's links I found a few relevant links but most have to do with engine swaps into YJ's and not CJ's. I want to hunt for an engine for my '85 CJ7 (2.5L 5spd) over the summer and try and do a full swap with a 4.0+ 6cyl with fuel injection over the next winter. However, I'm unsure exactly what engine/tranny/injection sets will fit into my CJ without too much hassle. I've heard I can get a '91+ YJ 4.0L into there with some minor issues (bell housing adapters, etc) and I've also heard some people have done various swaps of Ford/Chevy engines as well as a few XJ's but I've been unable to find any really helpful links as to exactly what vehicles I should be searching for to do this. I plan to visit the wreckers in a few weeks and would like to have a list of what is feasable and what isn't.

Thanks!

In California, a smog referee has to certify the transplant. The general rule is that the engine must be the same year or newer than the vehicle, and have all of the emissions equipment for that newer engine. There are other rules, which can be found on the DMV website. The sticker issued by the state tells the guy at the smog check station that the new engine is certified for the visual inspection and what to input into the computer so that it knows how much of what should be sniffed at the tailpipe. (Even so, some smog techs are idiots and it pays to find an inspection station that is used to seeing modified jeeps - a local jeep club can ususally steer you in the right direction.)

Jeeps R Us in Laguna Beach has done many 4.0 into CJ-7 conversions, and about a dozen V-8s from Grand Cherokees that I know of. After several frustrating experiences at the smog referee, they have the Mopar V-8 conversion dialed in and know exactly what to do in order to get the conversion sticker without too much trouble. (However, don't expect to call them for all the info you need to do it yourself. As nice as they are, and as helpful as they can be, transplanting engines is their business and they won't be able to feed their families if they give away the knowledge they worked so hard to learn.)
