harmonic balancers form 68-77 im told are interchangeable form the 350 and 400. I currently have one of each and are very different in shape and size although the timing marks do alline. the one off of the 400 is larger and has a rubber insert. the one off the 350 is smaller and w/o any rubber. judging by the looks of it im lead to believe it's stock but w/o the rubber im cuerious. the cast# on the 350 one is G146? any input would be a huge help :willy:
thanks
