I think we have found one local Model B block
 

City: Any

State: Any

I think we have a promising block found local

We need a better Model B 4 cylinder block long or bare if anyone can help. Our B4 is rusted through to the water in a couple of ports , yes they could be welded but we feel its not worth the added risk. It has also been sleeved back to std at some point.
Thanks Bryan .
