I have a 67 Sports fury convertible 383, it is a 4-speed. I've been told it's rare but I've never really checked into it. Does anyone know more about this year?

 

all 4-speed mopar's are somewhat rare, since the torqueflite was the main thing
i'll look up some production numbers for you

 

Big block Furys are pretty rare in and of themselves. MOST of these babies came with the 318. The 383 was the big block option, OR they could order a 440 from the dealer. The convertible makes it even more rare, especially as a "survivor" car. But I'd say that car is pretty low in numbers there, bud! Nice find.
