I do not believe that anything but the Allison 1000 has been behind the Duramax, including those in the Kodak and Topkick.

Correct.
But then again, there're no real differences between a 1000 and 2000 series, same max input (not counting pickup duty cycle) and same GCW limits. IIRC, the only difference is the 2000 doesn't have a parking crawl, so either air brakes or a parking brake drum on the output shaft / differential pinion input.
