Yes, the Ford 223 6 stick car bell housings have the same pattern for mounting the transmission as do the y blocks, the earlier FE and some early small block 289s. I am referring to the small 4 bolt pattern. Ford changed to a bigger 4 bolt pattern about 1965 I think. Some toploader transmissions had both patterns, some early ones had only the small pattern, and some have only the large pattern. These cases can be redrilled to fit the smaller pattern. There are 2 lengths of input shafts, small blocks have the longer one. These can be cut to the shorter big block/earlier length. There are differences in the size of the part of the throwout bearing collar that engages and centers the transmission in the bell housing. Everything must be measured before starting this kind of swap. Some early pickups use the same small bolt pattern, but use a longer and larger input shaft. Good luck.
