Although the oil distributor (or lack of it) isn't visible in any of the pictures I'm gonna bet it's a 216 due to the thin air horn casting and wide belt.
Stove - hang on to that book as I never had any luck finding the casting number from the 216 that was in my truck when I got it.
Fred - that filter housing was pretty standard on Canadian trucks. It was made by Donaldson and a repop sticker is actually available somewhere as they were used on other equipment such as tractors.
