Therian - Yep, some exxagerate the top-end numbers and low-end numbers. They have their reasons I presume.
Some post state that the difference between gt40 heads/AFR 205's and TFS2 cam/Custom cam and gt40/Systemax intake will net 150rwhp difference. That is simply not true by those measurements alone.
You see...I got Cobra intake, gt40 heads, "e' cam and they say "300rwhp tops"...well then you get I got Systemax intake, AFR 205's, and custom cam and you see "450rwhp is EASY"...lol. It isn't that simple.
