XJS V12 Performance specs question

I'm not up to speed on alot of Jag models but found a XJS V12 in what looks to be in pretty good condition but don't know anything about it.
Was just trying to find as much info as possible on this engine and anyone knew of popular swaps being done with them.

Thanks!

Well the motor will go out to 7.3 litres very easily, its a crank. Some ppl put 350 Chevy motor in it, I like the 12 tho its just a smoother motor. The one problem I can forsee is that its a Jaguar and probably will have some electrical problems but they can be fixed. I know someone who has one and wants to put another seat in it for his mechanic cuz it breaks down all the time... he just needs to restore it.
