Just from the numbers it looks like the hoses are the problem on the 5.0. The inside of that "crinkley" tubing is, on the scale of aerodynamic drag... about ten.........*G*.
To actualy get a test you must have an inlet PSI equil to the dynamic inlet pressure of the car under speed. That's going to be about .2inhg at aprox 80mph depending on where the inlets are placed. .2 doesn't sound like much, but the effect is pretty substantial as far as sweeping the cylinders and can make a good HP boost.
I'd try some smooth tubing and check it again.

Love hard, drive fast, wear your seat belt.
PS, that's my 'bird...... My Mustang is too ugly to take pictures of yet........*G*.
