| with any engine swap of different displacements, know right off that u will being doing some mods no matter what. everything will not fit up. as far as will the 400 fit in the 250 frame, well yes and no. idk if the tabs or in the same spot, otherwise you will need to weld new ones up. if u can do all this, then yes i would assume u could make one of those fit up in the 250 frame.
