Default 6.0L with Allison Transmission?

I have a bet going on with a friend, and he claims that he knows a fellow who just bought a brand new truck, either a heavy-half(1500HD) or a 3/4 ton(2500HD) truck that came with a 6.0L gaspot and an allison transmission.

Do they exist? Does anyone have one?

Thank You
Justin

I always figured that the 1500HD with the 6.0L had a 4L80E.

performance wise, i wonder if an allison (in a 6L) would be better than a 80e?

I got an 80e behind my 6.0

*Edit, According to the GM website the allison is not available with the 6.0.
