Hy Zaczac, welcome, your truck could have been built in Canada, and if it was it would have left the factory Chevrolet powered most likely. It probably has a 216 or 224 Chev. engine in it. If you could take a picture of the engine and post it, or as truckernix said find and post some casting (raised) numbers from the block and cylinder head, that would help us to identify what you have, hope that helps.
