The block started life as the old pushrod 170/250, then the crossflow with 3 cyl heads to sort it, then the sohc and finally the dohc.
Agreed, the block evolved from the 250 (I think they share the same bore spacing?), but apart from the starter motor and oil filter, I can't think of any parts shared between the pushrod engines and the SOHC's. Completely different animals.
