I don't know anyone else's experience but I used an aluminum flywheel one time and hated it. There was no inertia for letting off the clutch and I didn't like it for the street at all. I found myself burning the clutch more to get going and hole shots was much different. It was a 440 with plenty of power. Starting off in gear was terrible. Just a thought. I am sure the others have thoughts to share. Good luck. Great motor!
