Hy 72b4idie, it would appear that most Canadian light GMC trucks were Chevrolet powered, however I have a Canadian 53 GMC with a hydramatic and a GMC 228 engine. The GMC engine has a head where all the head bolts are at the same height, and the head is a plain rectangular shape, The Chevrolet engine has the head bolts at different heights, so the head is scalloped around the shorter head bolts. If your engine has not been replaced over the years then the number on the plate should be the same as the number stamped into the block just to the rear of the distributor, hope that helps.
