Whos running over 700whp on an 8.75?

I think there were three or four companies in that article. Not just one. Also, by the time I am done, I will have well under 1K dollars in my 9" including brakes and custom axles.
I was 1200 into my 8 and 3/4 and I'll be damned if I wasn't 1200 into my Dana 60...
