Clutch vibration
I just finished building a 408 i reused the old clutch from the LS1 it was a SPEC 3 it did not vibrate before. I'm just wodering if something may have caused it to become unbalanced.
I also added poly engine and trans mounts. The vibration does not feel speed related as much as it does rpm wise. It seem to vibrate @ 3,000 and up. Thanks for any HELP!!!!!!!!
