At what point to go Dana 60 ??????

I need to upgrade my 8.25 in my Duster. I've been looking at the S60 from Strange. The price is not bad for a complete package narrowed to my specs. I would entertain something less expensive that would hold up like an 8.8 but by the time you finish with everything needed, housing, new axles, narrowing, gears, etc. it seems the cost works out to be pretty close.
I actually have a thread where I went through the complete building of my Dana 60.
when I got the car it had a 7 1/4 that I tossed without even driving it. I put a 4 speed in the car and put it at 8 1/4 out of a Dodge Dakota with 355 in it $100. I had a Sure Grip put in it for $200. Got my Stroker motor and raced a couple weekends and figured I had better build an eight and three quarter before this one gets blown up. So I started with a 489 case. Brand new gears brand new spool brand new bearings all set up at the most reputable shop in town. 20 passes later Kaboom the Caps blew off the back. The thing is I spent the same $1, 200 building my Dana 60 and have not worried 1 minutes since.
That was my experience....
