Almost nothing can be used from the 1930 207.

I put a 1954 235 in a 1929 a few years back and here is what I used.

*1937-39 truck 3 speed.
*1938-46 truck bellhousing.
*1938-53 flywheel and clutch.
*1936-46 big truck clutch/brake pivot mount.
*modified 19 tooth speedo driven gear.

Your 1956 engine will have the longer lower water pump so that will need attention. I would recommend my water pump adapter for this problem.
