horse power VS 8 1/4 rear end

A lot. I have a friend who used to run a mid 11 second Demon hangin the skinnies over a foot leavin the line. Had an 8 1/4. He never broke it. He only changed to an 8 3/4 because he upgraded the whole car lookin for 10s.
That is the answer I was hoping for. I will more than likely never have slicks on the car so the 8 1/4 should last forever. Thanks
