His business is in manufacturing of smaller unit assembly parts with casting as a specialty. He delved into CAD work for the flathead V8 but was also making model A heads and such. He cast and finished a Model A block but that was some time ago. He sold off his 351 Cleveland block stuff some time ago to get funds for further design projects but to be truthful, life does get in the way of back burner projects for a lot of folks. I think we all know how that can go. I hope he makes progress. The world could use a new 8BA block and Burtz already markets the model A block.
