Agreed on the manual trans engines having an even number and the AT engines being odd. This is in the 6th digit position, e.g. 498058 & 498059.

And yes, the numbers are not necessarily sequential; as I stated in the earlier post, the 4980 series apparently doesn't exist until 1973, while the 4982 numbers show up in 1972 (the first B20F's).

But now about that 4981 B20A: what does your data say about where that engine was originally installed. 4981 does not show up anywhere in the 140 series parts catalogs, so it must have been installed in something besides a passenger car. Or maybe it was a replacement engine (or block) of some sort? The number is just weird, particularly since it matches known B30 numbers.
