You have at least a 1978 or maybe even a 1979 200 Six Short Block with the High Mount Starter. Plus one of the best of the Large Log Heads stock these will out flow any of the earlier 1963 !/2 to 1968 200 small log heads even if they were fully ported with big valves installed. They have the larger 1 3/4 inch intake valves, a larger 1 3/4 inch Carb mounting hole, and are designed to run on the current unleaded fuels. That is one of a late model about 1978 up large Bell Housing with the Cable Clutch Type with its matching Throughout Bearing Arm for use with the Larger 1967 up Flat Flywheels and the 9 inch Clutch Assembly. These later models also used the Diagram type Clutches not sure on which transmission that Bell was used with might of been the Top Loader 3 speed with overdrive or else the T4 trans if it happens to be for a T4 it would then also work with a T5 5.0 Trans swap without needing an adapter plate. That's a nice Bell housing and you can use it with a Cable Clutch conversion kit (such as the good one that's made by Mustang Steve's) this would give you a much easier operating clutch pedal along with using the later Diagram Pressure Plate assembly. Since it was an Automatic be sure if your going with a Manual Trans that it has a Pilot Busing installed in the center hole of the Crankshaft. Looks to me like a excellent engine with lots of the great up grade parts. Best of luck.
