This is for sure the intake..
The Dragon intake is ok.. It is a basic design, they do have good build quality and you will see basic gains. The Secret Weapon is the better of the two by WR. I have seen the Secret Weapon open up a Chevy 350 .. but I use the Injen on the B. As the only dyno comparisons I have seen show it to outperform most. K&N is up there, and a couple others that really designed the things for the B.
