Ok I have a 02' 35th collectors SS 6-speed w/ 20k miles Stg 3 SLP and here is what I want done.

I am getting Mickey Thompson street radials
Long tube headers
4 10 or 4 11 gears
An LS6 Cam or a little larger but not much
Electric Cut outs
Performance Power and Amp Pulleys
And I want a new budget priced rear end that can handle all of this with ease. But I don't know what rear end to go with. What would ya'll recommend?

Anything anyone would change and how much would I be looking at spending to get all of this done???

And I just got a Ported throttle body and Mass airflow that I just installed.

 

9" with a locker. a 12 bolt will do good unless you'll b hittin the track often. without the rear your lookin around 1000-1500 with the rear about 3500-4000
