I'm currently in the process of doing the same on my 69SWB but with a 350. engine mounts and their location can remain the same. The wiring will need to be modified if you were not running and HEI on the 250. Also, on my 250, the alternator was on the drivers side and for the 350, it was on the pass. side. Radiator Hoses will need to be changed along with the radiator and fan shroud. I'm not sure on your T400 as I kept the 3speed so I didn't have to modify from the tranny back.
