74 HEMI Dart Sport
my dummy block is a real cast block....unusable except for test fitting / mock up and door stop. Missing a chunk (removed to repair a different block I would guess) at the pan rail and has a couple of lifters stuck in it....perfect for what I use it for, test fitted into many a Mopar with it.
Mine came from Ray Barton many years ago.....I would think he has more in the same condition.
