Little vibration with LS7 setup normal?
Shouldn't vibrate at ALL, they're balanced perfectly from GM. This is the only clutch setup where my car HASN'T vibrated (steering wheel only in my case) around the RPMs you're talking about. God I love the LS7 clutch/flywheel combo 
You may've made an error installing it...

Did you properly break the clutch in?? Mine has never vibrated from day one & its been in almost a full year now.
The clutch setup has somewhere between 600-1000 miles.
Well I put the flywheel on and I still have the vibration and adding the pressure plate didn't make it better or worse; and I know for sure I torqued everything down exact to the GM book. I watched the harmonic balancer and it seemed to wiggle a little, maybe I'll buy an underdrive soon. Also noticed the engine hardly torques at all when I would rev the engine; it would move maybe 3/16 at the most. Maybe the previous owners put poly motor mounts in. The mounts are black and really hard.
At the time of the accident I hardly had any time to drive it with the new tranny and clutch setup. I know the driveshaft was out of balance so I can't really remember if there was any vibrations pre-accident. Maybe since the accident it cracked the harmonic balancer or something. It has never thrown any codes yet besides the skip shift error code.

If your balancer is messed up & your driveshaft is outta balance you'll definetly get vibration. Also if you do have poly motor & tranny mounts you will get a little more vibration.
The driveshaft is fine now I was able to fix that right before storage. I'll probably put everything back together and get an SLP banancer; hopefully that takes care of it.
Well I got the car back together over the weekend and got to drive it about a mile tonight. Everything seems fine, in fact you can't even tell there is a vibration now, me happy lol.
I guarantee your flywheel/pressure plate assembly is out of balance. I just went through this on with a centerforce clutch on my DD. Take them both to a machine shop that can balance them, it'll only cost you ~$30-40. You don't want to drive it much with the vibration, that **** is hard on the rear main bearing.
