Best rear for me What is the best rear for this setup.
forged 408 (~500+RWHP)
occasional N2O (300 shot (wet direct port)
373 gears
drag radials
street car
I Was thinking about a 9" because it is less likely to break
so what options should i get on the 9"?
I have a 99 w/o traction control!

Get a Billingsley 9" with a Locker. Do NOT, DO NOT get a posi with the 9"- the posi won't hold up to much abuse. The 9"/Locker combo is very strong.
No TCS is not a problem- just delete your ABS.

thanks for the info. Is there anywhere i can read about the differences between posi, locker and spool. I am an engineer and would like to know the mechanical differences between the three. I did search but couldn't turn up anything.

From what I understand, a posi will selectively distribute power to the 2 axles, a locker will lock the two axles together when there is a surge of power (while still allowing separate axle rotation when turning), while a spool basically has the two axles locked together all the time, basically making 1 axle (causing one of the rear wheels to spin/jump in spurts when turning to compensate for the smaller turning radius of the inside tire).
Someone with more knowledge than I, please elaborate, as I may have described something incorrectly in the above paragraph.

12 bolt: you want at least 33 spline
9": at least 31 spline
35 spline is pretty hardcore.

all the things southfl has said are true.
with that much power, you will want to have somthing back there you wont have to worry about. this is because running a 300shot of gas is going to cause more problems everywhere else and a stout rear end will be one less "weak link" to shut you down.
a 9" w/ a locker and 35 spline axles would be in mine if i was making 800+ hp.
p.s. - i have found that a "spool" is called so because it somewhat resembles a spool of thread (except its about 12" long) and has NO MOVING PARTS. it simply connects the axles together inside the center section and basicly gives you a solid axle.
with a 9", you can swap center sections around, simply slide the axles out enough to clear the locker/spool and remove the whole chunk. the chunk is center section that contains the moving parts of a 9". you can have one with higher gears and a locker for the street and maby another with a spool and lower gears for when you slap on the hoosiers and go to the track
