John,
I don't know what a 12 lb flywheel drives like, although I can imagine
you'll have some quick acceleration from a standstill and serious engine
braking when you take your foot off of the accelerator. I'm sure other
listers can speak from experience on the driving characterisitcs of an
engine with a 12 lb wheel.
More importantly, if this is a stock flywheel I would be very concerned
about its structural integrity. 12 lbs is pretty darn light for what was a
stock flywheel, which means a whole lot of metal has been cut away. It is a
possible that there is not enough wall thickness to keep it all together and
at high RPM it might decide to shatter. Let's put it this way - if the only
area where metal was removed is in the center section of the side of the
wheel facing the engine block then I would definitely be inclined to use the
other flywheel and cut it down to 15-16 pounds which seems to be the
reasonably safe typical limit.
