I had the same issue on a '55 and a '79. Motor mounts. When you get it back together, visually observe what the motor is doing when the clutch engages. Hotrod's chain idea is good. I fixed both my issues with new motor mounts. Do you have a tranny support cross member? Is the tranny bouncing on clutch engagement? Also check u-joints for binding; bent drive shaft.
