Pontiac had advertised durations that far exceeded the actual duration (which was no slouch for the day). And of course it matters where this figure was obtained from (.002, .005. etc)
Pontiac did this for class racing. If a cam had an actual 320* of duration, I'm not sure it would run!

I also had a real deal RAIV / 4-speed / 4.33 rear '69 GTO. Can't imagine what that must be like in a '69 Firebird!
