Basic Upgrades(LT1)

What are some "Must do's" to an LT1 camaro, might not be doing forced induction but if i do which would you suggest(company/site where i can find parts are helpful)

Exhaust including headers, some intake work, that way it breathes well on both ends, maybe a short shifter. There's so many things to be done, but what are you wanting to do with it?

intake and exhaust are in the car mod bible...i always recommend a cpu uprade(chip or pcm) because the factory programs em for eveyday driving and theres a lot of power wasted in the computer programming
