As others have said, rebuilding a 228 will be quite expensive and some of the parts may either not be available or not available in the size you need.
In 1977 I had a GMC 100 with a 228. It was a fine pickup...had enough power, rode well, sat straight and had no rust anywhere. I would compare the 228 to the 235. Actually for whatever reason the 228 seemed a bit less prone to suffer rear main seal leaks. It is just like the AD or Task Force trucks: the steering/suspension/braking are the 3 most important things on which to focus attention. Those are what can get you into trouble if they're not in top nick. Good luck!
