From what I remember the Chevy trucks with the big block had a higher tow rating than the trucks with a small block of any year. HP of these two engines were generally close, but the torque numbers is what set them apart. Perhaps GM disagree's with you as well?
Doesn't the GM 6L/6 speed/4.10 have similar if not better tow rating than the 8.1L/4.10? The 8.1L/4.10 was rated at 12k in the SUV and the 3.73 was down at or below 10k (around 9.6k?).
My 6L/6 speed/3.42 was rated at 9.2k. Pretty similar to the 8.1L/3.73 that had a gear advantage. My 6L would have had similar HP to the 8.1L and the 6L in the pickups with the 6 speed have more HP than the 8.1L.
Don't know... But I do know my parents owned a 96 Chevy 2500 with a 454/3.73 and later owned a 2000 2500 HD with a 6.0/4.10 and my dad was completely disappointed with the 6.0 towing performance compared to the 454 while towing the same trailer. He was sold that the 6.0 with increased HP would tow better and make better fuel economy while doing it was a figment of the salesman's imagination. The 6.0 towing performance is more inline with the 5.7.
