Bruce,
Yes you are correct about the Ferrari underfinanced 1969 Can Am effort.
I think the McLaren effort left the others scrambling. I don't think Roger Penske / Mark Donohue got involved then and the Jim Hall Chaparral H 2 project was a bust.
So as they say " the cream always rises to the top" and Bruce and Denny took full advantage of the situation but sadly that was all about to come to a tragic end on June 2nd 1970.
