1998 1/2 ton vs. 3/4 ton both with 350cid
What is the difference (besides the obvious engine) between these two rigs? Assuming the same suspension, transmissions and gear ratios, are they rated the same or does the big block account for a lot...

I have a 2000 C2500 with a vortec 350, 4.10 rear end, and the 4l80E trans. I've pulled upwards of 12K with mine. Te 12K day I was quite surprised at how well it did. OTHER THAN it did not have a WD, which would have helped from a how much wt was pulled off the FE. other than that, really no issues. I have pulled in the 6-8k range. It does every bit as well as the 4bbl/TBI 454's I have had, probably better with equal total loads. IMHO, the rating is a bit on the low side. The vortec is 255hp / 335 ft lbs of torque IIRC.
The BIG issue in my mind and past history, IS the blanky blank blank 4L80E trans. Behind the BB's I got if lucky 40K out of it. The 200 has 94K and still has the original 4l80e in it. Not sure it frankly is up to the task of BB torque, and still surviving. Then again, it has the tallest 1st gear ratio at 2.48 vs the dodge and ford 4 sp offerings at 2.7-2.9, and the GM 4l60e at 3.08. I barely like the low end on a 4.10 geared rig, would not want a taller RA of any sort! 4.33 or 4.56 would be better, but with out a DOD, that makes too many R's are 60-70 mph.
