To me it looks like a small block heater, look at the hoses going in behind the right cylinder head.

They might have removed the booster due to clearance problem with the head cover. If they don't change the engine stands to bigblock ones the engine sits to far to the left.

Look for where the front brakeline hoses are attached to the frame. If the bracket is mounted on the outside of the frame it is a drumbrake car. If the hose bracket is on top of frame it is discbrakes.
