Cone VS Clutch?

CUDA69 said

I have seven years, 25,000 miles and hundreds of passes on my Auburn cone LSD in a lowly 741 case. It's holding up on a 3700 pound car with drag radials and a 100 HP squirt. Granted its only seeing 430 HP on a 12 second car but it works for this application.

I am happy to hear you say that. Even though my Signet weighs in at around 2500 pounds, the cone I have in it has been through every small block engine Mopar has offered right up to two roller 340's I have had in it in the past 25 years... Where did we go wrong?
