<VV> Engine date

[4carbcorvair]

I have a 66 Corsa with a low vin of 2,1xx. The engine code is T0916RB.
I know this is the correct block for a 66 Corsa. Is the date close
enough to coincide with the VIN number? In other words, Is the Sept.
build date good, or should this have an August build date?

I'm just curios, this is going to be a summer driver, no concourse judging.

Thanks!
