I am a believer in the Danas if they are going to be subjected to serious low end power and moving a heavy car or truck, but if you have a light racer that pulls from 60 to 140 in the 1/4 then a 8.75 would be just fine. As an example is the Swinger from Canada that is posted today with the Gen 3 Hemi, a turbo, a PG trans in front of a 8.75 with 3.23 gears that just ran a PB of 9.29. Just a different way of getting the job done.
