Maybe the wildest, hairiest racing class of all time, the Can-Am series featured cars of unlimited engine size and few other restrictions.  The series attracted the ace drivers of the era and the top constructors.  The fun ended when Porsche out-engineered and out-spent the other teams and crafted the unbeatable 917/30 cars.  Everyone else quit and the series died.
