1500 HD vs. 2500 HD

[BlenderWizard]

I like to equate the 1500HD to the "Heavy Half" and "Big 10" options of years passed. I still wanna know where's the diesel in the 1500 and 1500HD?

Another quick thing that I noticed is; The 1500 HD comes with something like a 2 1/4" exhaust and the 2500 HD comes with a 3 1/2" exhaust. Both have the same 6.0. That might explain why the 2500 HD has a little bit more power.

VTISC007, are the trucks the same year? GM has changed the programming in the PCM and parts in the newer engines. Just my .

1500 HD is 2003, 2500 HD is 2004.

I've also noticed the difference in exhaust size both being 2004's & 2005's.

The 1500HD IS NOT a half ton at all, and is not simply a 1500 with a 2500 powertrain. The frames on the 1500HD and the regular 2500's are identical. Base option for the 1500HD is indeed a 6.0 engine with a 3.73 axle.

Ya i dont no wat i was thinkin when i wrote that post.
