Building a 6.0

[Twiz]

So, I'm looking to build a 6.0, can find a motor for around $1000. I want to build this thing as big as I can but keep it drivable. I've been doing a ton of research on this and know that a good cam and turbo can open up any ls motor. I have also read that if I want to cam it I need to swap the intake. I want to start my build with the cam and turbo combo and as I save money slowly work into the other parts, crank, pistons, things like that. But I don't want to buy a mild cam just to upgrade to a more aggressive one later once I upgrade other parts. So I'm looking for a good list of parts in the order I can install them.

My question is do I have to swap the intake for a cam? and what would some of you guys recommend for a somewhat of a budget build for this?

And because I know someone is going to ask I want to build the motor to drag race with in my 68 C10.
