Is anyone running a 4.7L???

I have to confess- I know nothing about this motor!

I recently heard a Grand Cherokee with a 4.7 drive past that sounded pretty healthy...though it may have been just a good exhaust system.

Does anyone run one of these motors in an A-Body? Are they any good? Are there any advantages?

Back of the envelope calculation shows that if you added 2 more cyliners to the 3.5L V6 (used in many Chrysler Models in the mid-late 90s, early '00s), you'd end up pretty close to 4.7L.... coincidence or do these motors share more than cylinder size?

IIRC, the 3.5L was all aluminum and pretty darned good for its day.
