Thanks, Jeffrey, I was just wondering if there was some more concrete
reason. Normally, I would agree fully about hanging "go fast" parts on a
tired engine ... but I recently found myself needing another flywheel and
there was this beautiful aluminum one sitting on the shelf ...
In all honesty, the engine seems to vibrate less with the aluminum. Not
sure why that is, but there you have it.
