What year is your CJ? There are plenty of classics with smog device exemptions around here. I live down by the beach in SO-CAL.
There are a lot of those California girls and you'd do really well with that CJ. California beach girls and Jeeps, now that's something they can't make better in Japan!!!

Back to the XJ though, I think the vintage 289 would not be much faster than 4.0, at least not enough to warrant the headache of adapting one to fit the XJ's unibody. It would just be for the uniqueness of it all. Out here people do all kinds of things to cars, but I have not seen a V8 swap with XJ.....yet. Plus you would need to be sure the C4 stays with the 289. The AW4 would not adapt well I'm sure.

Everything else will be good to produce around 15 hp. But thats not rear wheel horses though.

Also - try to get rid of alot of useless weight.

You misunderstood me. I was saying that I already installed all those that I mentioned.
I'd have to say that I disagree as far as the chip. Made noticeable improvement. As did the header, which most say cant be felt.

The 4.0L is capable of producing just as much HP and more torque than most small block V8's. Think about it... An I6 has 7 main caps but a V8 only has 5. The only thing missing is CID. I've been doing alot of research on 258 I6 stroker kits. 258 crank and rods gives you a 4.2l with 10:1 compression. Then bore it .030 over and you'll have 4.5L with HP and torque curves comparable to stock 5.0, 5.2, and 5.7.

I have never really got on my 2000 XJ, but back when I had my old '94 XJ with the 4.0L I6 and the AW4 trans, my 71 year-old dad was driving it and I was riding shotgun. Without warning he pounced on it and the ass-end dipped and I thought we might do a wheelie. The torque was like nothing I experienced even when my brother rented a Mustang 5.0 one weekend and we went cruising around. I am positive the 4.0 can be modified to compete with the Mustang 5.0 and certainly the newer Mustang 4.6. The only thing to watch out for is the stock rear-end. I am wondering if once the engine modification is complete, you should consider a beefier rear-end like a Dana 44 or a Ford 9 inch? I've hear the carriage bearings go out on the Cherokee's rear axel and have seen a lot of both Grand Cherokees and real Cherokees on the lift at the shop with the banjo pan off.
