A buddy of mine bought a 68 Dart that was somebody's project. He was told that the motor was a Moper Performance crate motor. It has a Mopar Performance dual plane intake on it. It ran pretty good so he just took it at face value. Now it looks like it needs a rebuild and I looked at the markings on the engine. Can anybody help me decode what this thing is?
