Hi to all, I am restoring a 1974 Cougar, starting with the existing 351C 4V engine. I've been reading alot of engine related posts, most of which refer to pre 1974 era motors. I have the original 1974 Shop manual(s) but I am wondering how much the 351C has changed from early 60's to 1974. I also have another parts car, a 1976 Cougar with the 351m/400 motor but I get it that this motor is not going to do me much good beyond a few parts and pieces.
So my question is how much has the 351C changed over the years. Thanks to all

Well the 351C was last used by Ford in 1974. So it has not changed much since then. The Australians used a 302 CI variant until maybe 1995? The aluminum cylinder heads sold for the Aussie 302 fit and work fine on the 351C, so I guess that was a little change in parts availability.

The 351C was considered state of the art in the mid 1970's for racing. These days it has ben surpassed by several other engines, notably the 351W. You can make more power for less money with a 351W compared to the 351C. Choices for any major component for the 351W are many. For the 351C choices are few.

The 351M or 400M both were never very popular for performance use and even fewer parts exist for them, even stock rebuild parts.

Thanks Leon - I thought they used the 302 C longer but you should know better than me.


Australia used the 302C and 351C until 1984 - last installed in the XE Falcon. Later V8 Falcons used a 302W from the Explorer
