Hey Bill, Thanks!!
So if the vin says it's a 6, and I find an 8 under its hood, then that means the engine was changed...fair enough.
I figured there would have been a few differences that would make a Canadian truck stand out, (even if just a different paint scheme...oh, now I have to find the paint/colors chart available back in '56) but if they are basically the same as the US trucks, then I'll just those as guidance when looking for my own
Thanks again!!
