You might want to wait for a few more opinions...... lol
I guess it depends on your power level, and application.
IMO, on the street, the regular 23spl A833 is about bulletproof.
Probably only 500HP, but 600 lb/ft. I think it won't be an issue with street tires, will never get traction at any speed, but if I put stickies on it the trans will be the weakest link (the Dana 60 will never break). Maybe I drive it until I can't... :)
