360 convert to 408. Throttle body

Yes, at minimum an intake manifold swap (M1 or Airgap) and 55mm throttle body. I run around with a bunch of Dakota guys who all run 408s and that seems to be it. They also run SCT tuners on the stock ECU.

A great place to learn more would be http://www.dakotart.com/forum/index.php

They know all about that stuff.
