appreciate the input!!!... hope to run it this weekend | | | Re: 318 engine vibration | Joined: Mar 2016 Posts: 339 enthusiast | enthusiast Joined: Mar 2016 Posts: 339 | Where does the vibration occur? If it happens at 55 MPH, find out the rpm that your turning at 55 MPH and then rev the motor IN NEUTRAL to that RPM number. If the vibration is gone-it's not the convertor.
