Dealer said it's just the nature of the beast, no need to worry, It was a question I figured I would ask since It was going there any way. The rest of the story on the 4 wheel drive is in the other thread though, so if your interested go there, otherwise thanks for the replies, I was curious if this is a commen symtom, seems to be. like I said earlier my 85' 302 has a very rough idle and has had it from day one so I figured it wasn't anything major, as stated before just the nature of the beast.

If we were talking about rebuilt high-perf motors, we wouldn't be dicussing the little "wobble" 
I think it's a combo of things, such as light rotating weight so you feel every tiny little difference in firing at idle, lots of things.
Who knows, maybe the injector pattern isn't perfect at idle...

there IS a counter balancer in the drivers side head, my guess would be that the engine isn't, nor can't be perfectly balanced. I have a little puke*sputter*wobble once in a while at start up but otherwise it idles fine. It isn't an engine that I have to look at the tach to see if it's running though (not that I have a tach). But she is mighty smooth and friendly, more so than any other engine I've ever owned.

Like I said before, I knda figured this was normal and it is just a smooth as silk except when I'm stopped and its just idling. I then get a little blip every now and again. I figured I might as well ask since it was going in any way.

Actually, my '01 V10 seems better balanced than my 4.6l's ...
The rear-view mirror is rock steady no matter what in the SD ... the 4.6l's do vibrate a little bit around 2000 and 4000 rpm... The V10 is smooth as glass...
