Boy, that was a long time ago and many other modified air boxes have wielded to my hand tools.;f
If I remember correctly, I simply drilled a bunch of 9/16" holes in the sides of the airbox below the filter level and away from the engine (heat issues)...I also smoothed out the drilled holes with sand paper and removed any silencers.
Here's a pic of the custom air intake I built for my `92 F250 with an EFI 460 for about $80:
