It is possible for the car and engine to have been built the <span style="font-style: italic">&quot;same day&quot; </span>. The car build date (actually build <span style="font-weight: bold"><span style="text-decoration: underline">week</span></span>) is probably derived from the cowl tag (A-D representing the 1st thru the 5th week of the month). This is the <span style="font-weight: bold"><span style="font-style: italic">WEEK</span></span> that the assembly of the car was started, but it may not have been completed that week. The build DATE of the engine is when the assembly was actually completed per the Tonowanda stamp on the engine pad. So it is POSSIBLE to occur. I remember several well-documented/authenticated cars with engine assembly dates and car build dates being very close together. However, I am not saying this car is as reported or that the engine pad stamping is original.
