Anyways your cam depends on what youre gonna do. Turbo, supercharged, NOS, N/A, it all depends on what kinda set up you are going to do, all different cams work better for your specific application, like my cam is a good all motor cam but also works well with the juice, anyways jump your ass over to ls1truck.com and ask this question there is an abundance of guys over there that will give you some good info. I mean i could sit here and tell you everything, to get it done, plan on spending at least around $5,000 thats if you do all the work yourself and just shoot the spray to it.

wow... It sounds like you have some learning to do yourself.



Why do you want a twin setup? You could easily attain your goal with a single turbo, and it'll be much cheaper.
