TR3 and TR4 Engine Blocks

I finally finished cleaning out my storage shed preparing for the rebuild of the shed. I have 3 bare engine blocks that are of no use to me. The TR3 blocks are TS11276E and TS17050E. So if anyone is seeking an engine number that is closer to their commission number, here they are. I also have a TR4 block (CT36803E) that has a problem. The ring that the starter attaches to has broken off. I have the broken piece, but I have heard that cast iron is almost impossible to fix. Is this block garbage, or could it be of use to anyone?

Due to upcoming construction and my son's wedding, I will be very busy for awhile, so these blocks will be available after mid-October. Of course they will be pick-up only (about 70 miles NE of Detroit). Let me know if anyone would like these, otherwise they will be offered on Craigs List.
