[V8Vairs] Flywheel - Aluminum or Steel?

[Ken Hand]

 ??? On the subject of flywheels and shock loads, keep in mind that the Corvair differential can take pressure it just will not take the shock load of a drag strip start. Most differentials don't break on deceleration usually but rather when you put to much power to quick.
??? It is correct that you can put more power to the diff with an aluminum flywheel but the shock load is greatly reduced overall, mainly because of the reduced rotating mass. If I were to own a V-8 Corvair and I had the choice, I would use the aluminum flywheel.

"Extra flywheel mass makes cars idle better.  Also it acts as sort of a
"shock absorber" between the engine and transmission, evening out power
delivery."

Also my opinions. A heavy (heavier) flywheel acts as a shock absorber by
resisting the rotation of the crankshaft under acceleration and
deceleration through inertia. The crankshaft reacts to the tendency of
the flywheel to maintain resist acceleration/deceleration by twisting.
Whether this is good or bad, I don't know but I have my suspicions.
