There are MANY LS2 cars that dyno 340-350 on a regular basis, I've seen some in the mid-high 350s.
I know this is kinda off-topic so I apologize for the semi hijack here, but do car companies purposely underrate engines for insurance reasons (i.e. if you rate the 335i at 300HP, then you get a slight break on premiums compared to a car with like 325HP?) I always wondered about that.
