AAAlright let me make this simpler to read.
Bought wrecked 96 trans am running perfectly
Installed lt1 into my camaro pic in sig
After installing the motor I noticed it shook at certain rpm more than others.
The car had an electric water pump on it so I kept that
I also replaced the clutch when I swapped it
Did a bunch of other things in sig I've even modded it since installing and the vibration is still there.
But keep in mind I removed the pressure plate and disc and only flywheel the engine still has that weird rotating vibration
So I messed with the balancer rotating the hub 90 degrees and trying it.
It was still there. I even ran it without the balancer on and only the hub still there.
After that I decided to get the flywheel checked out by a machine shop.
Even discussed with them about lt1's and that it's externally balanced on the rear.
They balanced the flywheel and pressure plate together and sprayed some paint to mark the pressure plate orientation.
However now with it apart I'm unsure what they did as there are many drilled holes and even two in the molded weight on the back.
From what I have read there isn't supposed to be alot of drilling at all.
So that can't be right.
Is my flywheel out of balance? or what?
Should I buy a flywheel?
Or Is my crank bent or something?
Only reason I replaced the clutch was that the pedal felt high but come to find out that is the way it is. Lesson learned.
Now why would it still do it without the clutch, before and after balancing.
I guess I will try a flywheel then a balancer and then motor mounts.
If none of those then I guess it's internal ?
