I recall when the 351W came out it was mostly snickerd at and not taken seriously. If you wanted real power, the 351C was clearly the best choice.
So whats changed? It took YEARS for research and development to become more common place for the 351W to get decent power out of it at a reasonable cost. Whereas the 351C faded away, without any real world engine developement work done (as with the W engines).
Today it's just easier, cheaper to build a W to respectable levels than it is to build a C. I have GREAT respect for the Clevland and am always pleasently surprised when I see one. Go for it!
