You will need the paper work that came with the car to prove any claim of originality. I used to put 409's in my 1953 Chevy two door coupe but that didn't make it a rare 409 SS car (made it a fast hot rod though). Anyone in the past fifty years could have installed a 409 in place of a stock six cylinder and you have no way of knowing for sure as you can replace every part on the car with service parts available when newer that converts it over to a 409 car.

For a list of the parts you would need to change (and check off your laundry list to see if any one who changed it missed any) look at this site.

They are the acknowledged experts in this area.
