This allowed the use of shorter ...
From 1977 onward, the 351W shared the same head casting as the 302, differing only in bolt hole diameters (7/16 inch for the 302, 1/2 inch for the 351W). Early blocks (casting ID C9OE-6015-B) had enough metal on bearing saddles 2, 3, and 4 for four-bolt mains, and as with all small-block Fords (SBFs), were superior in strength to most late ...
