The company I used (can't remember their name offhand) did volume V6 block castings for Mazda and Toyota and differential/transmission housings for Chebby. There were other OEMs they did business with too. Contrary to other thoughts here, the OEMs also have significant problems with aluminum castings too. Technology, high dollar machinery and processes can't "mitigate" all porosity problems. It seems like it's just the nature of the beast.
