3 questions =)

Also i want to put a cam into my car, but dont want to replace anything else like pistons or anything. But i wana upgrade whats the biggest size you guys recommend going what type...size...ect. And will it make a big enough diffrence to even upgrade (keeping in mind i only wana replace cam).
And last but not least what size throttle body should i put on it. I wana go for power obviously. but have no idea what size nor make model ect.
I have a 2001 ws6 trans am. ram air. and nothing done to engine. Only thing i can see is i have a aluminum driveshaft.
Thanks for all your help guys!!!
I know im retarded let the bashing begin.
(2). You cant just replace the cam, you will also need new springs, and a timing chain wouldnt hurt either, Also better pushrods will help. As to size, It all depends on what you want to do with the car, If its aminly a street car, then go smaller, this way you will have a healthy power curve, and wont feel sluggish at low rpm's.
Also for a big cam to work, you need better heads, the stock ones will hold you back alot if you get a huge cam.
(3). First try and port your own, or purchase from one of our sponsors a ported stock TB.
If you've got the huge cam and good heads, then go with a FAST 90/90 for optimal performance.
For a cam thats your own chioce look at others reviews I Like the MS3 cam but you would prolly want to do more to your motor before it.
As for the TB I would only do that if you did the intake as well.

bolt on to do:
Intake:
BG Ram Air
Larger MAF (I had gains, but some people dont)
ported Throttle body plus bump stop mod (the stock TB is good for over 400+ horses!
You DONT need to change your intake manifold, you have the ls6 manifold and its great one to have!!
Exhaust:
Flow through muffler or exhaust cutout/dump (your decision)
high flow cats or no cats (your decision)
ORY-pipe if not catted
Long Tube headers
Engine:
Underdrive pulley
Chassis/suspension:
subframe connectors
Lower control arms
torque arm
