There is a local car forum in my area at my college and someone said they blew their LS6 engine last night while riding around. He has reported some problems about clanking before he blew it up. He said it knocked a couple of times before it blew last night. He says he has never used NO2...... anyone else hear of something like this..... He "might" have been bouncing off the rev limiter right before it actaully blew that trying to do a burnout in a parking lot. I'm sorta confused can that really happen?
