Rare Dodge Dart GT? Which engine is this?

True, I heard somewhere that it’s on the opposite side because it’s classified as a race engine though. Again I can’t confirm that in any way because I haven’t found much about it yet online :/
I haven’t read the whole thread yet but first thing, welcome aboard.

Second thing about the race block…

No you don’t have one unless there is a letter “X”, “R” or a “R3” located in the picture below. The early race blocks were cast with the same numbers as production blocks.
