Slant Six engine numbers issue

in 1970 the "B" code was for 225/ 1bbl,
and where your Vin has an "8" in the seventh position, my decoder has letters for N.American production plants.

Thank you for clarifying! i always thought that "B0" meant 198/ Carter 1bbl. If i'm not mistaken the "8" means Export, which would make sense since this car was assembled in peru.
