Yeah...so we stuck the bore scope in it and cylinder 3's piston is fubarred. It's got detonation damage, pitting, and from the looks of it a huge chunk is about to come off. It's probably my fault for driving around without a way to check knock after I started modding. I think I'm just gonna sell it and try to find another trans am to put my lt1 in. Lesson learned.
