anybody ever done it, if so how much fabrication would be involved and is it even worth it. i know they made zj's with aw4's so i guess thats what you'd have to use

The V8s didn't use AW4s only the 4L so you'd need the tranny as well.

the 93 4.0 ZJ had the AW4 NOT ALL 93 ZJ'S have the AW4..

And the AW4 will not directly bolt to a 5.2/5.9...

interesting to know, btw this is all hypothetical

Thats too much work for only 30-40 increase in horsepower. I know its hypothetical, but id go with a hemi or a small block engine if i were to change. Someone on here has a Chevy 350 in his, but he bought it that way.

You could do a mopar 408 stroker..

DUDE454

Ya, i forgot about a stroker! That makes more sence than anything. Good call.

Gee oh Dee

You'd still have a ton of custom work to do, on top of the cash for a stroker.

Wouldn't a GM350 be really cheap, easy to find, easy to get parts, and be the same amount of work as the 408?

4.7 5.2 5.9 are all small blocks just like a 350 small block which is a 5.7 and they are all about the same h.p.A hemi can and has been done but we dont have that kind of money to blow.So you wont be doing that one

rich

Maybe he don't want a chebby to ruin the jeep there, and no it wont be really cheap and easy at all

rich

It can be done Ive seen a 360 (5.9) in a mj and an xj. It will cost a good chunk of money but if you can fab and weld and do electric, you can do itYou can run a 727 4wd tranny or the newer ones to. Also you will be able to ru n a 205 trans case which is one hell of a case.Many options on trannys and transfer cases also good choices of which motor,Just quite a bit of time and money will be invested.

Gee oh Dee

You missed my point, big surprise.

I guarantee you'll find a GM350 for less than the total cost of a 408 stroker, so yes, it would indeed be cheap.

And just as much fabrication would go into the GM350, so ease of install is a wash. You still have to fab, one way or the other.

I can see not wanting to use anything else but a Jeep motor, though.

Cheap and reliable.

if you do any kind of engine swap its going to be a major headace....

Right, that is what I was getting at. Any swap will be a headache. But, as I was saying, with as many GM350s as there are out there, the 350 wouldn't be a bad choice. They are cheap, and easy to find parts for, both OEM and aftermarket. You can also make a 350 into a stout motor, but you can do that to any motor if money isn't an issue.

Those 5.3s are pretty good motors as well. I helped a buddie of mine do a HG on one, not too tough to work on.

On a side note, with all the bracketry and such that GM puts on their motors, I've found them to be one of my least favorites to turn a wrench on.
