Apologies - I had to go to bed (after emptying the loft of old car books, did I mention I would avoid Google...)
4 valve engine was a Peugeot GP car. There is a link because Bugatti designed a Peugeot car but not the 4 valve one as far as my book said.
On the plus side I now have a pile of old car books to re-read...
I may indulge Google for the fuel filler one though, not being familiar with US cars.
Bendix, who are they ?
EDIT - Lucas, lest we forget...
