Yes, that's correct, although I don't know how loud an aluminum FW is... never tried it. Other than that, you are dead on...

No Bogus, I am the one that posted another thread about this since I don't have access to the original FW. I am balancing this this weekend. I hope this will help!

I was just checking out Carolina Clutch and they do offer LT1 performance kits which replace the DM with an aluminum SM flywheel.

Has anyone tried these packages?

Do these packages make the awful noise Bogus is describing?
