ok, the problem is stated in the title. I have just put in a 347 into an AOD car and I have this annoying vibration in every gear from about 1100 to 1500 rpm. It does it in neutral, in park, and while the car is moving. I turned the ignition off while going down the road and still got the same problem. The engine is balanced to 28oz and so the damper and the flexplate are matched to that...what do you think the problem might be? Do you think it wasn't balanced correctly when I got it or what? Does the converter have to be balanced to 28oz as well? Thanks for any help.

well, if it does it when the engine is off, then i'd rule that out as a cause...leaving tranny/ds/rear as the problem.

or maybe the front bearings/alignment

also...if it does it when the engine is off...then i'd think it is speed related rather than rpm related
