Does anyone out there know how to deciper this number off of what I presume to be a GMC 228 engine? The number stamped onto the block is as follows: A228293305. I just need to confirm that it's a 228. It's definitely a GMC with the old GMC script logo on the valve cover and about 5 other places, including the head. Just need to know what I'm working with here. Thanks, Neil
