Started on the 65 Valiant today

Anybody ever seen a factory 273/2bbl/ 4 speed Valiant 4 door with 9" drum brakes all around? Everything is original, #'s have been run and confirmed as a V-8. I have searched all over and cannot find anything that indicates changes or work done to the car. SO # on fender tag is 907. Vin is V85251****
Just surprised to find the 9" drums after I jacked it up. It has all the V-8 parts it should have, vin on title and car match with no indication of being messed with. What's up here?
