There is something quite baffling about Ford's decision to discontinue the 351C.
It is apparent that they felt the 351C was not a viable power plant to adapt to the new pollution control measures being implemented at the time. Preferring to go back to the Windsor engines as they felt that design was more easy to adapt.
But then they continued on with the 400C and later the 351M, both using many 351C components and designs.
Surely those two engines would have been as difficult to modify, from a production viewpoint, as the 351C when it came to pollution issues ?
