I know that is the same time frame you went from 1/2 tone to 5/8 tons trucks to get around pollution standards. Who knows. As mentioned, probably just to save a nickle on retooling the emblem. I am getting to old to remember that far back

I have read many times that it was to skirt the smog laws, above 400 Cu In had less restrictions. 1970 and later 396 and 400 were actually 402 Cu In.
