its apparently pretty damn easy and well documented as far as swaps go.
I hear the stock gearbox and cooling system will have to be upgraded, but the engine mount kits are plentiful and not too expensive.
Just try doing a couple of quick yahoo or google searches for jeep 350 swaps and you'll get some great documents.
I'll probably do a 350 swap on my CJ next year. This year's project is gonna be the body work :-D[addsig]

There are a few ways to get around this one.. the easiest is to call novak or advance and get the adapters you need however like in a previous post that v-8 is gonna be rough on the rest of the drive line, especailly the transmission, dunno which jeep you are talking about but either way you have to take it easy, me being me and loving inline 6's I would call clifford and look into rebuilding the 6, trust me it can make all the power you will ever want with a good rebuild and the right parts..

To each his own, but I'm against dropping anything into my Jeep that is not a Jeep part. Most Jeeps around here are just Chevy drivetrains under a Jeep body. I want to show people what a complete Jeep can do. Thats why I'm dropping in a 258, even though I have a friend selling a 350 for cheap.[addsig]

AMC should have felt the same way about parts in their Jeeps. It seems like my 83 has more GM and Ford parts in it from the factory than geniune AMC stuff, guess it was cheaper that way.
Anyway, I've got a fuel injected 350 and an SM465 waiting to go into my CJ. I need an adapter between the 465 and the D-300(about $400), motor mounts(about $100), wiring harness, chip, fuel pump(about $500), and custom exhaust($300-$500). Good thing I already had the motor, transmission, and fuel injection. :-O
Then there is the rear issue, because I'm figurin' that the AMC 20 ain't gonna like it. Looking for Scout 44's for it, if anyone has a line on a set, or at least a rear somewhere around NJ please let me know.

I would say to upgrade the transmission as well...the 700r4 is a good transmission to toss in there.. no electronics to worry about... and as far as physically putting it in there... get some mounts, mock it in to there.. find out where everything else needs to be bolted to, then make mounts from there... if you are doing this... a ford 9" is not a bad idea[addsig]

i tend to agree with jeeppicus.... why not just build a chevy? and from my experience, no engine swap is ever easy, especially if it entails a drastic change in size. If you want some more power get the supercharger and bolt it on to the 6 in an afternoon--- still a jeep with comparable results.[addsig]

a supercharger is a supercharger... if they make one for something, its made for all.... not mounting it and making it fit is a different story... since we have a low compression ratio, we are cabale of a good amount of boost... you can always slap on a 4.0 head and intake (not quite "slapping it on") and use the 4.0 supercharger[addsig]

Yup you can supercharge any engine, even you 3 HP Briggs if you know what you are doing. BUt without boring/stroking/blowing or any of that.. well ok an overbore may be necessary for the rebuild.. anyhow the 258 can be a beast with some good old fashioned hot rodding. Look at it like this if the wings and bling crowd can get 2.0L honda's to run in the 9's you can get a 4.2 L to run with a 350.. Trust me here.. take a look at Clifford performance, they specialize in 6 cyl performance. The V-8 is ok but why be like everyone else I am so sick of the 350, yes it is a good engine but it is BORING, I am a car nut but I am so sick of car shows because you can easily predict the drive line in just about any vehicle, jeep or otherwise. 350/350/9 inch... Just to make A point my next project after the CJ-5A is a 1972 AMC Hornet. The plans are laid for a Hesco or Golen stroked 4.0 out of a cherokee (blown) and backed by a Tremec 5 speed, now hows that for original? ANyhow dude the point is love your 258.. just like fat chicks they need love too..

Oh and for the details.. lets see, like some one said go with a 93 and up 4.0 head, have the ports cleaned up DO NOT ENLARGE THE PORTS just clean it up, get a nice 3 angle valve cut, get pistons that will bring your static compression ratio up to right about 9 - 9.5 and a decent cam, say like an advertised duration of about 268 or so and a good header, intake manifold from clifford and a 600 cfm carb of your choice and there you go.. recipe for 300 HP.. Oh and get a real ignition from mallory/msd etc...
