I am assuming you have the "bigfoot" gearcase on that engine. If so, the vibration you are getting is most likely clutch rattle. On that engine you should be using a Flo-Torq III hub kit, designed to eliminate that problem.
It sounds to me that a 13" pitch might have been a better all around solution, which should bring top end up to 30-31 mph.
