Quote: I can't recall which flex plate you had and I don't feel like reading 6 pages to find out if it was a weighted unit but I assume you do know that generally a 340 is internal balance and 360's are external balance? As such, they require specific harmonic balancers and converters/flex plates. If you install a converter that is neutral balanced on a 360 that requires an externaly balanced converter and damper, it will shake like he!! Same thing the other way.
i do have all the correct stuff for the 360, as for ther 340 im using everything from that motor,,,
