266 V8 in a 1961 Truck???

I was helping my dad pull out an engine out of his 61 international truck and i saw stamped on the drivers side front of the engine the numbers 266. when we bought the truck, the last owner said it was a 345. My question is how can i tell for sure what engine we have? Did international offer a 266 in for that year?

Also, i was looking around at the Binder bulletin website to find some info on that engine and not finding much of anything, but what i did find is a chart that lists the horse power and a few other things. What i found out is the 266 made more HP, more torque, and is lighter than the 304. If this is true, why did they discontinue the 266 and stay with the 304?

I owned a 1960 with a 266 V8, 1 ton. What I remember, the 266 heads are smaller and oil filter sys. is what you found on tractors of the same era.
