I don't think 60 ft is going to be relevant.
There are several people on this forum that have been in the 8s on either turbo. There are a couple here in the low-mid 8s on the S476R.
76mm turbos have been in the 7's on 3000+ lb V8s. A billet Borg Warner S476R with a 96mm wheel and a race cover should be capable of 1200 whp.

my daily type driver on a standard 475 t4 and a 302 with low boost went 1.58@60, 6.20@117.5, and 9.55@148. 3400 lbs, standard m/t 275, 3.25 gears... and mine is nothing special at all compared to what some guys are doing.

Stall speeds in the low 3000 range are common. I don't think I've seen lower than 2800 or higher than 3800. I went with 3200 stall triple disk Circle D. I'm also going from a billet to cast wheel for x235, although I don't think I'll make it out this year since I don't have an 8.50 cert cage yet.
The S475 is capable of 5.60s without pushing it to the absolute limits. There are guys running mid 5.30s around here on a cast 76.
