lo po cam dilemma

I don't recommend cams cuz it ain't my money. Occasionally I do recommend what cam not to buy, or not to install, when I see a recipe for disappointment, in a certain combo.
It is my opinion;
that the 6400 needs an Scr over 10.5 to be truly effective below 3000, When saddled with 2.76s, and a stock TC..
IQ knows facts. Way more facts than me,for sure.
