Well here I am spending another beautiful saturday pulling out my hair. I recently completed my magnum 360 swap on my cordoba. I opted for the v belt setup so I had a reputable shop build me a nuetral balance converter. I am using the flex plate that came with the 360 magnum and a blueprintengines dampner with different attachable weights. The car drives smooth but has a light "pulse" at certain rpms. I have a loose piece of trim on the dash you can hear vibrate as if the car has a pulse. The engine idle is constant but i definately can feel that there us something slightly off. I then ordered a mopar branded dampner from jegs that is the correct part number for a 360 magnum seperate from the crank pulley. Even in the description it says it is for running v belts with this motor. Well.. i install it and fire the car up with no pulleys and it shakes like a demon. Any suggestions or ideas as to what I am facing here?
