Mopar 413 Motor Serial Number

I have a Dodge 413 motor out of a 65 Dodge Semi truck. I found RB in block casting and stamped in front of the exhaust manifold behind the water pump is GT 413. Does any one know what this is? Where do I look for the actual serial number?

Thanks

I guess my question is, "what is your real question?" In other words, why do you even need to know the serial no?

On the later BB's the serial as I recall was stamped, not cast, into the pan rail.
