The "New" cans are predominately old UltraDyne grinds that were brought to Lunati by an old UltraDyne employee (at least that is the story and UltraDyne appears defunct)
As for personal experiance, I've got a 405A1 I hope to have running within the month.
For further cam reccomendations, we would need to know what you want from the engine. (IE: rough idle, high rpm power? You willing to buy a converter?)
