I have a 1951 4400, relatively all original if you don't count an old paint job. All the serial numbers date to 1951, so it's intact. My question is; why is my truck only rated at 85hp, and why is it a 216. Everything I can find lists my truck as a 235, and all 216's should have 92hp. I've read that Canadian trucks never got the 235 and they had lesser horsepower, my gauges are in miles per hour I do know that Canada switched to metric in 1971. I'm thinking I might have a Canadian truck, I did buy it in northern Minnesota. Thoughts? Thanks, B. Kelley
