Reminds me of the old Ford engine that Ford stopped manufacturing because it wasn’t breaking down enough to be financially pragmatic (as in the cost of repairs). Same concept here I guess. Semi-stable product = semi-unstable profit.
remember the DeSoto? it was wonderful.
Last one like that after the FE block engines was the inline 305 6 cylinder. A friend had one in a pickup and got 250,000 miles out of it without opening it up, back when 100,000 was considered a very mature engine...
