Throttle stop ratio question

For all you .90 racin experts: 427 SBC in a nova runs 9.3 all out. Gonna do some S/G with an alky carb setup as follows: 54-5500 dead/down stall, shift .80 out, Tstop on @ .30 & off @ 2.5 to run close to 9.90 in 2-3000 ft DA. What kind of T/S timer ratio am I gonna end up with? was thinking around 5-6 to 1 with what testing I have done so far. Also any ideas on a good starting point for an air ratio? 60 ft repeats pretty good (about .010 swing all day) Thanks for any replies
