360 engine vibration

I am following this and also and have always had some vibration that I also believe are from my converter weights. When I had the converter installed they were overlooked and not tack welded on. Major Vibrations from car when driving and revving in neutral. This was years ago and I still remember it was bad. I contacted the shop and they tacked some weights on the converter whilst on the car. Not sure if it was done perfect but bad vibrations were gone. There is still some vibration around 2000 or so and it has been like this since 1991. Trans is toast now so New Converter and Trans planned. Car is a 1970 Duster 340 with a Mild 360 and 727.
