Whats is worth 8 3/4 with suregrip, drum to drum, 3.91's

Yes after I got my stroker I did the same thing with my eight and a quarter. I took about 10 or 15 passes with it and was thinking man I better sell this before Kaboom! I sold it and built an 8 3/4 what's a 489 case brand new spool brand new bearings brand new gears and brand new 35 spline axles with green bearings. Blew up on my twentieth pass! Put the same again $1, 200 into a Dana 60 and have never look back...
I think my 83/4 would live quite a while, but i'd actually feel bad blowing up a mopar rear end, that has value to someone else (And me when I sell it :) ) 9 inches are plentiful, and worth less..lol
