That was my only concern was if the 6.0 could come close in the torque curve to the 8.1 or if the big block blew it away down low.
I there isn't much difference I'll most likely go with the 6.0.
I'd love a duramax but the initial cost is about 4 times the other two options and I can do a lot to an ls motor with an extra 3 grand lol.
