Engine squeaking and tapping.

I went to the track and ran 12.1 @ 125 on street tires with a 100 shot on torquer v3 car. 2002 ls1 m6 trans am.

Cooled down, went again, bad launch, aborted that run and went again.

Strong run but my engine stalled at the end on decel. I heard some metal noises inside the engine, and it kept dieing. we noticed it is squeaking and tapping. I feel the tapping in my shifter. Fueling seemed alright on the way home but it struggled with rpms.

I drove it home, 40 miles, it made it.

Did i kill a bearing? Or is it a bad lifter? I checked rockers and springs, they are all good.

if you can feel it in the shifter i doubt even more that its a lifter.... im in agreement with these guys as i was saying on aim.
 
Sorry dude, it's toast, pull the pan and feel the rods, one will be as loose as Jenna. In case you don't know, the engine comes out the bottom.
 
Ill give ya a hand with it jon. Time to start thinking about what the new motor is gonna be, cause it probably wont be a 5.7L :)

And yea, it is incredible you made it 40 miles back with that thing!!
 
spun rod bearing. dude my car sounded EXACTLY and i mean exactly like that. if i closed my eyes i would think i was watching my video.

and this is what i found when i pulled mine apart.
