390 & 351 Cleveland question.
 

Does anyone know if a 1964 390 engine out of a galaxie can be a direct replacement for a1974 f250 390? Also the guy said it has original fmx trans but I thought fmx trans wasn't available till 68, any thoughts?
Finally my last question I have a 1970 ranchero with a 351 4v cleveland, would a 351 Windsor be able to connect the the same transmission if I took out cleveland?
