Just curious, if you had to guess, how sure are you that this is off the LS9?
The reason I ask is because I put it on craigslist and a guy is telling me that if its off an LS9, it can only fit that engine, which is apparently hand made? (Again I know nothing)... but he said if it was off an LS6, it is much more popular = easier to sell.
So, I guess my question is how can I tell exactly which motor its from... NOT that I don't trust what you are judging from the pics, I was just curious what the determining factor is between the version... am I looking for a measurement that would tell me for sure?
