So many people have added V8's to the front of the air cooled Beetles which I'm sure is a ton of work but how hard would it be to make a couple hidden air ducts from beneath each fender to the radiator and keep the hood original?
There's definitely a better way. When my buddy and his family have done it, the hood stays stock and shuts. I have seen louvers added. It really just depends on setup, but I'm with you, the white one is just wrong.
I don't have any better pics, but this is a SBC swapped car that I helped work on years ago. The hood is stock, and I don't remember cutting on the front apron.
