Seriously... what rear end to use?
All I can find is opinions. There are no rock solid facts anywhere, at least not that I can find. I want a rear end that is good up to 800 ft/lbs of torque (wont ever get there) but is made for the street. I read ppl saying that the S60 sucks on street but is the only thing that will hold up to that kind of power...

I would do some more reading, because your kind of off base with what your posting. There is no rock solid fact to point to what to use, because its really just personal preference.
The S60 doesn't "suck on the street" it has to do with what differential is being used.
A 9inch or S60 with a spool either would hold that power. If you want stock like driveablity then go with the 9 inch and a wave/s-trac. The wave/s-trac both carry warranties and are supposed to handle that kind of power.
People think S60's suck because they are heavy. With a spool you will not break it, but the same can be said about a 9inch as well.

spool is drag only. This car wont be drag raced. I want 3.42 gears and the only reason I want a rear capable of 800 and not 600 is cuz I want the tranny and rear end at the same level.

I am perfectly happy with my 3.73 moser 12 bolt but if you are looking for specifically 800 ft lbs I'd probably toss in a 9 inch. I don't know if you can get 3.42 ratio in a 9 inch though? Heavier and stronger than a 12 bolt but lighter than the s60.
FYI - trans and rear end don't have to match that power rating 1) if the engine isn't putting out that much 2) if you never plan to race with slicks or drag radials

Get a taller tire if you want to get closer to the 3.42 gear.
Id vote 9inch Wave trac
I beat the hell out of a 59 Ford 9inch Rear with a C7AW-E Non Nodular case and 31 splines Moser axles..
Parts are plentiful and get a spare 3rd member for quick gear changes.

Im in the process of building my own 9 inch, so far I have all the parts (on order and paid for) for less than 1700... If you go with a 9 inch be sure and get a nodular carrier and use a "daytona" pinion support. They have larger pinion bearings and can handle a little more torque. aftermarket cases are plentiful and cheap. A few vendors have the mosier bolt in housing i think.

been running a S60 w/truetrac w/4.10 for 3-4yrs now (about 12,xxx miles)
-street driven
-drag raced
-auto x
for the money it cant be beat.
yeah the 4.10 howls a little, and the torque arm likes to hit the floor board tunnel, but that's part of going faster with reliability.
