Jim,

When I first built by 67 Camaro bracket car many years ago, I had the same problem with the TH400 behind a fairly decent small block. First time I just wrote it off as a fluke, second time six months later, my trans builder said "the drive shaft is out of balance" I could not feel any vibration going down track, small block turning around 7k rpm but . . I had a new shaft built and never had the problem again.

Might be at least worth checking.
