the dont work well on a street driven N/A motor. they usually only make power in the upper RPM range on a N/A motor.the last person i know that tried, lost almost a 1/2 seconds in the 8th buy changing nothing else but a box manifold.

If you dont have runners, you dont have tourque down low. If you dont have boosted power you DON'T want a bread box. You car will feel like a turd.

I agree the runner length is critical with the torque curve you cut the length you cut the torque, you lengthen it(to an extent) and you gain torque, breadboxes were built to take advantage of blowers to get the boost to the valve quickly. stay away from boxes without a blower as a rule of thumb.
