Weiand 7510 Intake

Might I suggest the Holley Street Dominator? It is BY FAR the best of the single plane intakes in that category. It has a much larger plenum than the rest, which results in WAY better low end torque than you'd expect from a single plane. This is the one you want, not the later one with the divider wall.
