Wow did I misinterpret this thread title.
I thought this thread was about the new 6.7L Cummins diesel. Wow was I wrong.
I was in the 1994 Northridge earthquake in California. That was a 6.7. Not fun. We were on vacation from Utah. We were sleeping on the floor when it hit. A curio cabinet fell on me and a grandfather clock missed my sister by 2 inches. Her stuffed gorilla bear took the hit instead of her.
