4.0 history

I'm curious about the history of the 4.0 engine. I know it's based on an engine AMC introduced in 1964 (and powered a bunch of Gremlins a while later), but at some point AMC (or Nash) took a clean sheet of paper and designed a new engine that eventually evolved into our wonderful 4.0.Does anyone know when that was and anything about the orginal engine?Jeff DeWitt
