Also the engines got quieter and smoother and more powerful over the years. The 3116 sounds like a clothes dryer full of rocks compared to a C7.

Agreed. However, I will add that the 3116 zips the lighter M1078s right along. I've never driven a C7-powered M1078 for comparison, though. But, I do have a C7 in an M1085A1. More power...and your opinions are echoed here.
