Would this work for 11's?
 

I have SLP LID, Kooks LT's (soon to be installed), full exhuast, LS6 Intake Manifold, tuned....

Could i break 11's with a daily drivable CAM and aftermarket heads (+ the rest of the valvetrain)?

Or would i need a small shot of nitrous? :)

or would a turbo kit on low boost break 11's for me?

EDIT: I'd like to keep my gear ratio at 3.43

yes it will

u mean 3.42 and yes you should be able too if all your stuff is matched up

am i gona need an another Diff?

Is this a M6 car? Your gonna have to leave really well which means an aggressive launch with slicks or hooking d/r's. The rear-end is a liability. There are a bunch of florida f-body guys that go to bradenton motorsports park all the time. I'm gonna say no on your question, it's possible, but difficult. On spray you could launch the car softly, have the spray come in at 3K and easily get in the 11's no problem. Would also be easier on the rear-end.

It's goin' to be a lil tougher with a M6, but with a A4 you should be there.
