Automatic flywheels do not have a clutch surface and are simply stamped steel with machined ring gear around the perimeter. With that, they only weigh a few pounds.
If you weigh the rotating internals and the torque converter of the 4F27E , you will be surprised at the total weight (I am not even talking about the gears, just the clutch and drum assemblys).
Also trying to removing a few pounds of rotating mass does almost nothing for throttle response, there is just too much spinning weight which is seen when you dyno an automatic.
