What makes a 239, a 244?

I have seen several flatheads mentioned as "244"s, instead of 239's. What makes it a 244?

I ask, because the motor I just bought is a 244. I have seen 244's listed as being bored .020 and .030 over...so it seems like it's not just boring that increases it. Wouldn't that be stroke?

Thanks in advance!

It is just the bore - see my post in the 48-60 forum for details.

Increase in stroke is usually noted in fractions.
