This car would be of Canadain origin...here is the only info I have been able to find on their V8 numbers:

I have no information on location, but would be strongly inclined to concentrate the search on the left and then the right forwar frame rails first.
On the engine number...as with US, I believe that would actually be on top of transmission casting bellhousing, and that is the master number.
