I was just curious if anyone knew about how many 8.1 2500HD's GM puts out a year. I just don't see that many usually just the older 2001-2002 models. I bought a 6.0/4.10 last year and like it, but almost wish know I would've just bought the 8.1 with the Allison since they seem to get about the same mileage as the 6.0, plus the Allison is really nice for towing. It sucks that they are thinking about dropping the big block for 2007 HD's. There is just something about a GM big block!

I'd like to know that too. I searched the internet with Google but nothing specific came up. Not even a total production run of Silverados in general.
