I'm waiting to see what my 4.0 decides to do…but I've been throwing around the idea of pulling my 4.2 out of my Trailblazer and swapping it into the XJ. Anyone ever thought of swapping out the AMC block for the GM surprise?

I'm also debating about putting the 4.2 in a 48-54 Chevy 5 window…which I'll do if I find one before the 4.0 craps out.
