need help on intake manifold decision

If you are talking about the box intake from Down's Ford from Toms River, NJ, it requires the use of forced induction to be of any use. It will kill the drivability of a stock or near stock 5.0L. otherwise it is a well regarded intake for boosted engines.

What would it do on an engine with Trickflow heads and a TF stage 1 cam. I plan on going FI in the future, i just dont want to kill my bottom end in the mean time. Any thoughts?
I have 3.73 gears by the way.
