Pad Stamp Tonawanda L48

[WaltZ]

This 4 bolt large journal short block is in good shape, std bore, original 3.48 crank, rods pistons and turns over smoothly
before i dismantle it and send out for cleaning and magnafluxing, I'd like to know what the vin #s might mean
TI004HN:
Tonawanda, October 4, 1968, 300 hp 350ci, 350 turbo hydromantic.
... the 00 are not the same?, I have heard of similar differences on other Tonawanda blocks including an I used as a 1.

the vin numbers are what I can't' figure out.
naked eye looks like: 19201276
with photo enhancement, the 9 may be a 3, the 0 may be a 9, if so: 13291276
please see picture.
any help is appreciated.
and thank you in advance,
Walt

I'm going to guess that it's a 350/300 with a Turbo 350 from a full size passenger car assembled at the Oshawa, Canada plant, but I'll have Warren take a look and see what he says.

thanks Ed, looking foward you your thoughts and insights. The  previous owner had it in his garage for over 40 years and believed it to be from a ss 350 camaro, but who really knows. thanks

Maybe it was a replacement in a 68 Camaro before he got it?

Guessing it is from a ST Therese fillsize car and the last digit didn't get stamped for some reason
