Chevy 454 partial vin identification

I have a 73 c10 that came with a 454 originally (CCZ) but the current
454 is probably not the one that came with it...

The 'partial vin' number on the front of the engine is

TO412TRH
37CE91593

I think the TO is Tonawanda, and 412 might be April 12, ....

What else can you tell me about the motor????

I was not able to find a 'partial vin' reference site...
That mortec link gives a reference for block castings (used for various
vehicles, for a range of years).
I think the 'partial vin' gives the more specific information when and
where it was made and maybe which vehicle it was for???

I'm not sure where the partial VIN is on a Big Block Chebbie but it
contains the GM division(1=Chebbie in this case), the factory the truck
was made at, and then the six VIN sequence digits. If this doesnt match
the VIN on the dash...then its not the original engine.

SBC has the partial VIN on a machine pad just behind the alternator.
Maybe BBC is the same?
