That is nice. It does appear to be a 1 ton pickup, not all that common. Maybe a 3/4. It should not have a 216 as that is a Chevy motor. Probably a 228. The valve cover should have the GMC logo. On the block is a flat behind the distributer there is a stamped number. The first three digits tell the size of the engine. Any GMC up a 302 will bolt in. It would make a better stocker than a rod because of it's size. A great push car or parts/equipment hauler. That way you could keep and use the bracket on the rear fender. With a rear gear change it could do moderate highway speeds. 3.55=55-60 easy. Great find. You'll find a lot on the Stovebolt site. Beater
