[V8Vairs] Flywheel - Aluminum or Steel?

[Thomas, Robert R Civ 76 PMXG/OBPE]

"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.
