I still say 12-14psi, cam and 5.3L (like oringally posted above) will not get 650whp, there has to be more to it. I didn't say the block won't hold it, I said a few will make it hold, but generally speaking, when someone asks and they are told to make an "easy" 650hp, that is not possible.
Just so it's clear, 12-14psi, cam, with stock 5.3L, will not make 650whp, that much pressure doesn't equal that much power.

I agree, But i dont remember saying anything along the lines of 'put XX amount of boost to make XXX amount of power'. Every combo is different, its just a matter of getting the combo tuned and making it work.

It may not be as easy as some make it out to seem (myself included) but its still alot easier than some may think but it does take some playing around.
