Hi Kempy, having read this first thing this morning and now tonight I see it's had 147 views through the day with no response surprises me. Even though 427 Cobras used FE engines as did Super Cobra Jets they weren't fitted with this type of intake. Given this is also an Australian page on the forum where 99% of builds here are can't, by regulation, use the FE engine or elaborate performance intakes like this, I think your'e asking the wrong crowd.
I thought someone would would chime in with a view as we're all gear heads, however think a more relevant forum would offer more feedback.
You haven't included in you're profile where you are from, so I'm assuming Aus as this is an Aus page. If so, FE's aren't that common here so you're market is somewhat limited. It could be worth good coin, more so if it were a factory setup as that's what demand the dollars.
For all the reasons above, I would have no idea what it is worth, but best of luck moving it.
