I'm surprised at how powerful the 6.2L V8 is in the GM trucks. That would be an excellent powerplant for the 2500HD. There is obviously a reason they have never put in in a HD truck, but that 6.2L & 10 speed would be a sweet combo in a 2500HD.

GM does not consider the 6.2 a heavy duty engine due its aluminum block. That was in a GM publication a few years ago that was on the fleet section of their website.
