I don't like the engine to move for a couple reasons:
-It can shake the exhaust apart. The heating and cooling cycles cause enough issues, that I don't need it banging into somthing else and shaking it apart. The last two vehicles, at least one pipe was close enough to rattle off a frame rail or somthing with a rubber mount. I don't need the leak or the agrivation.
-It really doesn't provide much of a noticible difference. If you have the engine tuned well, and idleing well, it should be fairly smooth. It all depends what your willing to live with for a cam. Its one of the reasons I like EFI so much. It takes that nasty cam and tames it a bit.
-I find its also more consistant on the R/T and ties the frame togather nice for a little extra rigidity.
