Cold Air Intake-need input

[lnirenberg]

I am trying to put together some options for cold air intake for new EFI on W-head 409. I will be going old school and drawing air from the inner headlights through hard 4" tubes so volume shouldn't be a problem. I attach pics of some things I have found but would like other appropriate options ie the air box on top of the throttle body has to have some mass given the vintage and physical size of the engine. The attached pic of the spectre air cleaner can have the snorkels at any angle and I would likely go with 120 degree angle and with the billet piece I would use in line filters. I appreciate any ideas anyone has. Thanks in advance, the sun is out and it is time to go drive a car!
