    What are the biggest differences between the internals of these motors, and are they interchangeable? I'm pretty sure they are, but a friend of mine is curious, and I can't find any resources to confirm this.

    Thanks.

    99/01 = aluminum block, non forged internals, worse flowing heads

    03 = iron block, forged internals, better flowing heads

    i think thats the gist of it. someone correct me if i am wrong.

    You forgot to add that 96-98 Cobras are SUPERIOR to all, becuase our intake manifold looks soo damn cool. :nice:
