My 58 fury was a 350 b engine my 59 was a 383 RB engine and all 62's were 361's b engines, Except for some of the Dart 440's they were 318 poly's unless they had polara trim. I never saw a 383 b in a 62 and I bought many for parts. They were 361's if they were a big block unless they were 413's. You could get a 426 Max in late 62 but it had to be in a Polara or Fury ordered for a sanctioned race team. Only ever saw one in my life time it was a Fury.
