This is exactly what I have been asking about. The only thing is that the VM44 has a bigger air bell than the PWK39. If one of these could fit a zilla chassis with a VM44 or Lectron style carb, than we would be on to something. On a side note, I saw somewhere where drag racers were experimenting with zilla and DS-650 intakes. What does a DS-650 intake look like & has anyone here tried one?
