Gears & Axles - 800 rwhp + 4l80e = what rear end?

I am thinking that with the amount of power I want, I'm going to need a beefy rear end to support it. This will be a street car but it will be run from a dig on the street every now and then. Should I bend myself over and pay almost $4000 for a Billingsley fabbed 9" or would a Strange 12 bolt hold up, considering it will be behind an automatic? I want reliability but the tranny setup will cost around $5000 by itself. The thought of spending $9000 and still having a stock motor really scares me but I'll do it if it is a must.

Are you looking to keep your abs, or it doesn't matter?

Doesn't really matter to me as long as the brakes still work well for daily street driving.

Better get the 9' incher with that type of power 12 bolts are tough but the 9 is alittle tougher!

Wow, that is very nice. I did get your PM and will definitely consider your services when I get my LS1. Can you build the 9" so that I can install it myself without all the bullshit issues I hear about with Moser units? Thanks,
T.J.

EDIT: Do you have a web site? I searched via Yahoo under "Driveline Solutions" and a shit load of results came back.
