"I had hope with Ceramics and Aluminum Ceramics and for some reason those ideas went away in the 80's (with the Chevy Vega)"

Vega didn't use ceramics in its engines. It had an aluminum block and head, and the car was famously troublesome.

But now, thirty-three years later, aluminum engines are commonplace.

The world has yet to see a ceramic automotive engine in production, however.
