Kidding of course. Ford design was a "work in progress" as evidenced by the three bolt Model B water-pump.

Ford engineering noted a number of improvements needed for the original A engine as the A was produced,but Ford held them till the B engine was introduced.Most noticeable was the main bearing issue,Ford engineers knew of the A engine weakness of the crankshaft and the propensity for center main bearing failure during engine development.The issue wasn't addressed till 1932,with the B engines bigger main bearing journals and pressure lubrication.
