Please ID this hood

It is indeed a Boss 429 style scoop, and they are readily available from a number of sources. Check around and you should be able to find one for under $100 easy.

That is a Boss 429 scoop. Standard on 1969 Boss 429. It too I believe was non-functional though, but any scoop could be made functional.
The Boss 429 scoops were indeed functional, directing air into the air cleaner assembly that sealed against the bottom of the hood.
