Build 8.75 rear end or going for the Strange S-60?

but if you spend a couple hundred or couple thousand more,

It's never just a couple hundred more.....

It's never just a couple hundred more..... 

and it never ends! You do one thing then the thing next to it doesn't look as good and so on and so on....

Lol, we put it differently for a BOAT (break out another thousand). No difference in cars these days, eh?

 Do the Dana .... do it once do it right
The was a magazine test years back they took I think it was a Dart to the track ran 1/2 dozen passes with the 3.55 8 3/4  then swapped to a dana 3.54 & made 1/2 dozen more passes the times were virtually identical in the 1/4 but faster in 60 feet as the extra weight planted the tires a bit better .

The DrDiff ( Strange S60) is lighter than the original Dana, not sure exactly how much though.

I had it out for a gear change and I weighed it with my race car scales. Without brakes, with axles and caliper brackets, tru trac , oversize axle bearings, 4.10 gears ect... it was 204 Lbs.  I'd be curious to know what a stock E-body Dana weighs to compare? They advertise the S60 to be lighter than a stock Dana?

I tend to overbuild stuff as I don't mind spending the money once. If your going to run BFG T/A's street tires then your likely fine with the 8 3/4 if it's in great shape. Me/my thinking for my car was I built a motor with almost 2x the stock output, spent the money on a stout transmission,sticky 200 tread wear rubber, the rear end then I figured was the weakest link so I went with the Dana and sold the 3:55 SG 8 3/4 while it was still in one piece. I didn't want any headaches down the road as I had no idea how many miles were on the 8 3/4 ? Having everything new is no guarantee it won't break but at least I know what I have age wise.
You just need to decide how/what the car will be used . If it's just a cruiser with the occasional drag race then the 8 3/4 should do fine. Tire selection will be more of a deciding factor than anything else.

  A DANA 60 does look BAD ASS under an E-body though! Your choice!
