8.75 Strength?

My thoughts is that the 8 3/4 has the strength of a 9 inch and I've seen many 9 inch rears in very high horse powered cars. I find builders including my conversation with Nelson engineering tell me one of the reasons persons use 9 inch over 8 3/4 is because of there are many around, yet the 8 3/4 built right will do the job. He also said that weight being overkill on many vehicles which include building a Dana for something not needed.

As far as building a 727, when I got mine from Dynamic, Frank Lupo said it will handle anything I could throw at it and it does. Maybe not everyone can afford certain items, but when you build a 1000 hp motor, what exactly does money mean?
