The head flow is fine...the weight is fine...
now its just a matter of the conv and the
right gear with the right cam... W-2 heads
flow only about 310 cfm on my 416 and my
Rampage is only a less weight (2900#)
EDIT
What heads are yours... thats a ton of flow
for .600 lift... but you should be low 10s
wave
