The 400 is the crank to use. It has the same main size. Some macheining has to be done to the nose to make it work. There is aftermarket cranks are readily available and are cheaper than trying to use the factory one.

to install a 400 crank in a 351M NO machine work needs to be done as they are the same except for the stroke. the blocks use the 429/460 bellhousing, and engine mounts.
