Aluminum flywheel vs Steel and Clutch ?

[Bobcat]

Second what Undy said on the flywheel . My 427 Galaxie has a big heavy cast iron Ford flywheel .... but it also weighs 4100 lbs and has a 4 speed . An aluminum flywheel would make the car almost undriveable on the street . My Cobra has the aluminum flywheel .... light cars can use a light flywheel as they get underway easier .... heavy car needs the flywheel inertia to help get the car moving , not stall the engine or have to slip the clutch a lot .
