Rare Dodge Dart GT? Which engine is this?

Is the motor stuck?
Automatic or stickshift?
We incessantly tried starting it in 2020 without luck. Turns out the carb had a crack in it so I’m guessing that’s why it failed. The fan turns and it sounds like the engine is a second away from starting. It’s a 4-speed manual, “sinter clutch,” it seems like the car was made with racing in mind.
