gear drive

I have a Pete jackson" Noisy" gear drive on in my 440.

I love it and it sounds so cool when Im flying down the highway
I have driven 5000 miles so far and no problems
I had read posts that the engine would vibrate apart from harmonics.

Why when you can by a belt drive well WHY NOT its america
Note : I switched to full synthetic from Brad Penns motor oil of the same weight and the gear drive quited down?? I switched back to Brad Penns!
I had to make a small modification to the timing chain cover but thats all
