    So I've had a vibration in my 347/C4 combo forever and it finally dawned on me that I might have the wrong balancer on it. It a late model 5.0 so when I bought the balancer I bought a 50oz for a late model. Low and behold, Coast High Performance balanced it to 28oz. I put an old 28oz balancer I had laying around and voila! Vibration is gone. :) Now if I can just keep the damn leaf springs from wrapping, I'll be golden. :)

    Might want to try set of the HD 4 leaf springs, traction bars or both.

    It's very common to balance 347's to 28oz..... My question is if the balancer change made it better, what flexplate do you have on it(50oz or 28oz)?????
