Upgrading to a GT is the easiest route of course, but that's not a point I usually make, being a V6'er myself .
FWIW, a F/I 4.0 is quite fun!

Yep, engine work is not required. And you can have a lot of fun with just bolt on F/I.

For me, I'm running the X on a stock bottom end.

If I ever get to the point of wanting to do heads, cams, and bottom end, I'll do a V8 drive train swap instead. Cheaper and gives you room to grow.

One drawback is the extra weight balance toward the front end if you're into more than just straight line.
