It's not too bad yankin the tranny to check the flywheel. I have had a few friends with cracked Ls1 flywheels....
Car is launching hard! Could really use a BMR swaybar out back......

If its a 2001 or 2002 my bet is it cracked the flex-plate,as they are weaker than the 98-2000.If you pull the starter out you can see pretty good at it,look at where the bolts attach to the converter,and crank.

Drain the oil and see if it looks metallic/silver. That will be a good indicator that you have spun a bearing.

Had a really nasty noise once upon a time and a few people thought it was a cracked flexplate, turned out to be a broke valve spring causing the limp valve to be smacked up by the piston...

Sounded like a gnome or something hitting a frying back with a ball-pean hammer...HARD.. in my motor..
