Bullitts have the ability to suck in and expel more air. It's there in black and white with the intake, throttle bodies, and Arvin mufflers.
More hp in lower ranges is not the answer to this question.
How could any of these three be a detriment?
They aren't a detriment, but they also may not be the bottleneck for airflow.
Why is it that aftermarket exhausts that worked so well on 5.0s are not worth much on 4.6s?
Why is it that larger throttle bodies on 5.0s worked so well and are not worth much on 4.6s?
Those aren't the bottlenecks in the air pump. The intake may have helped some, if nothing else it moved the powerband down some and broadened the curve.
I'll say it again, the performance difference between the 2 is marginal.
