Give you one example our canadian GM documented impala ss427 has it's original engine stamped TO1113T from the plant you refer to.You won't find that in any of your books and if you were buying the car would probally say it is a CE block that I stamped but right in the GM docs same number. Why??? did that same plant stamp a canadian block differently. Because it was coming to canada.........Just like she didnot have smog

I'll connect those 2 concepts. In Camaros, they didn't use a unique assembly code for non-smog export cars. Big cars are a higher volume and may have used a unique code for export (no holes in the exhaust manifolds).
