slant cam guessing game...428 lift?

Well, if you can, measure at about .005" lift to get 'advertised'. It is tricky to do and get consistent results.

And of course the cam makers measure advertised differently. Lunati measures advertised at .006"; Crane mostly does it at .004". That makes the Lunanit VooDoo's look more aggressive, and the Cranes look bigger.

I'm looking forward to see what you come up with.
