I used to port the crap out of Street Dominator manifolds, oout of the box they flow about 270 if I remember what 440Jim posted but ported they will go 310 plus. My ports usually wind up 1/2 way between 906 and max wedge size but since you have standard port windows prolly wont pick up that much.

I agree that the cam is a good choice for a no prep stick car, pretty narrow torque/HP curve which is perfect for a light stick car
