Hear is a ? for ya about HEMI A bodies

I had a 64 B-Body NSSA car that ran 10.0s with a 500 inch Max Wedge. I folded up an un-braced 8 .75 like a cheap set of monkey bars. I went Dana 60 and never had a problem after that. IMHO 8.75s are for street cars.
you`ll now when it`s time to switch to a dana, when u start blowing an 8 3/4 every other week end !
