It's the weight you should go by,Heavy = Dana
Based on my observations a 283 in a heavy Car could be thougher on rears than a 396/427 in a lighter car.
Trying to move a lot of weight from standstill in a hurry is what takes a toll on stuff.

My experience with 8 3/4 is that they start breakin up around 3500 pounds and even earlier if you have some serious power.
Then some say the Dana is faster also...sorry about the rambling,your question was about the 8 1/4 and 8 3/4 and I have zero experience with the first one!
