Just wanted some help on a project that i plan to do with my 66 f-100.....It now has a 351 from a 79 ranchero and i purchase a 352 that i want to install in there to make it back to its original state. Does anyone know if the tranny it has now (71 ranchero i believe) will fit the 352 i want to install in there or do i have to replace the bellhouseing or what....Can Any one advice me on this issue.....Thanks much
