57 Chev people have a hard time dealing with a Mopar that upstages them . Most of the mainstream car mags have given the 1 for 1 title to the 56 B. Even though I don't have one ( wish I did ) , everyone seems to leave out the 57 DeSoto Adventurer that was 345/345.I believe it was the first American auto to have a 1 for 1 engine as STANDARD.
