I experienced similar symptoms with a 1985 Ramcharger (318 V-8) I had
before I got my Dakota. At certain highway speeds there would be a
vibration that seemed to be coming from the engine. Slow down or speed up
and it would go away. Turned out that the main pulley (the one connected to
the crank that drives the accessories) had three of the six bolts missing
and the remaining three loosened up over time. I discovered what the
problem was when the three remaining bolts all failed at 70mph and the
pulley departed for parts unknown!! Pretty unusual deal and I've never
heard of anyone having the same thing happen but it's something to check.
