Oh, they'd do 90. but from what I recall they all had a strange cyclic harmonic vibration to them. I had three Americans and it just seemd that once you got above 60-65 they had this vibration. It didn't rattle your teeth or anything, it was mild, but it was there.
  Could have been tires, u-joints but I always put it down to the engine itself. Just what I thought at the time. IRRC they were all 196 cars that did this. Now that I think about it I don't see how it could have been the engines as my 63 Classic seemed much smoother, I remember the cast iron motor being smoother running then the aluminum one that wouldn't take the abuse of a 17 year old kid.
  Doesn't really matter now. That was 30 years ago.
