It is possible, but electronics and transmission are different for the 4.2. A good used 4.0 is going to be the simplest, most economical option. There are lots available.
Also see Jaguar Specialties. There is a kit available for an LS1 conversion.

Your '98 model year engine is an AJ26. Jaguar changed to the AJ27 in '99 which had different wiring harness, VVT's, cruise control, cam position sensors, throttle body, ECM, etc., etc., etc. . . . Basically, the short block is interchangeable, the long block with some modifications. To use the complete AJ27 is where all the expense begins. It can certainly be done but best with the doner can sitting next to yours.

But as said I have only done it for SC cars.

I'd go with the LS1 Conversion if it's an older XK. The older engines/transmissions are a bit anemic. If you had a working SC engine, the TS kit would be better for you. At least if you're after the most hp for the $$.
I've been drooling at that conversion since I first read about it. I've decided I'm putting my money into my 05 XKR instead of my 97 XK8 so I'm getting Avos's TS kit. If I had chosen the XK8, it would definitely already have dropped the LS1 into it.

I'm on a budget so the ls1 is not an option. As far as determining whether my car has a AJ26 or an AJ27 could I check for a number on the block? My xk8's engine was dismantled when I purchased the car, I have the engine out of the car so it would be very easy for me to locate a number on the block.

If the engine is toast and you're pushing 100k on the old tranny, an LS1 swap may not be as expensive in the long run, especially if you want performance mods in the future... The 4.0L NA is pretty limited, IMO.

Thanks guys, I found the correct replacement engine with 77k miles. Cring! my car has 124,000 miles and I have no idea if the transmission has even been touched. Are the 2000 xk8 transmissions better, and if so will the newer transmission work with a 1998 engine?
