I currently have an eighty six ford f150 that I am going to be swapping motors in. I was wondering, if the 351w, and the 351c both bolted up to the same bellhousing. I have been told that the 351c was from a different engine family and that it would not bolt up to the same belhousing and then I have been told that they are from different families but these two share the same bellhousing. Then I have been told that they are almost the same exact motor, one was made in windsor canada and one was made in cleveland ohio and that they shared bellhousings. Thanks for your help.

The 351W and 351C are from different engine design families, but they do share the same bell housing bolt pattern.
The other engines in the 351C design family (known as the 335 series) are the 351M and 400, and they share the bell housing bolt pattern of the 429/460 engine family (385 series).
