If you measure the length of a 1941-54 engine with the water pump installed, you will find that it is the exact same length as a 1955-62 235 with the adapter and pump installed.
The problem must be that your engine has been mounted forward from stock, or at the wrong angle, or the radiator is back from stock.
Looking at your pictures I suspect it is a engine positing problem.
Is the engine mounted to the crossmenber in the original position?
If so I suspect it is the angle your engine is mounted that is causing the problem.
