DOHC hemi A925

I think I read about that engine back in the late 80s.
It never got past the valvetrain testing spun with electric motors.
Was breaking Alcoa aluminum plates or something like that. Never run on
a gasoline powered engine before it was outlawed and development ceased.
The doomsday machine was the magazine title If I remember correct.
That was along time ago, never heard anything new about it since.
